Tweek Tweak, voiced by Matt Stone, is a fictional character in the animated series South Park. Even though he is not one of the five main characters (Stan, Kyle, Kenny, Cartman and Butters), he was a main character in season six and was the second replacement for Kenny after his "permanent" death.


Tweek Tweak is a jittery 10 year old boy, addicted to caffeine. He seems to have very extreme hyperactivity caused by his ADD, as said by his parents in his first appearance; episode 17 of season 2. He is always seen shaking, twitching and looking around frantically. He constantly feels like he's "under pressure", and freaks out whenever he is asked to do even the simplest tasks and jumps or yells whenever someone comes up to him to talk to him. He tends to scream at the end of his sentences.


Tweek has blond hair in a spiky design looking as if he just rolled out of bed, wears a green shirt buttoned incorrectly, and blue jeans. As revealed in "Tweek vs. Craig", he weighs 48 pounds. In "Gnomes", his physical appearance was slightly different than in the more recent episodes. Instead of a green collar, he had a black one, and his jeans were also much darker than in later episodes.


The character's name, "Tweek", is derived from the term "tweeker", a term used to refer to people who recreationally use crystal methamphetamines, or to people who exhibit a high level of stress or anxiety. Originally, Tweek's surname was spelled as "Tweek", implying that, similarly to Eric Cartman, he was called by his last name. However, in later episodes, his surname was changed to "Tweak", though his father's name tag still reads "Richard Tweek". In the official South Park site's FAQ section, it was verified that the character's name is "Tweek Tweak".

Caffeine addiction and ADDEdit

Tweek's parents own a coffee shop, called "Tweek Bros. Coffee", and they continually supply Tweek with coffee. He has become addicted to the beverage, and has high caffeine levels in his system; making him extremely jittery and paranoid.

Tweek's parents are oblivious to the fact that he is overdosed on caffeine, believing his shakiness to be brought on by Attention Deficit Disorder, although ADD would not cause shakiness, but merely a short attention span (Attention Deficit Hyperactivity Disorder, or ADHD, would cause jitteriness). Interestingly, despite his parent's beliefs, Tweek goes with the other kids to be tested for ADD in "Timmy 2000". Believing his parent's claims, Tweek tries to control his "ADD" with Transcendental meditation, and sees a psychiatrist, Dr. Norris, who tells him to "find his center", as a way of calming himself. However, when he expresses his stress, his parents attempt to calm him with coffee, thereby increasing the level of caffeine in his system and worsening his mental state.

The staff at the official South Park website have stated that together with his addiction to coffee, Tweek does indeed have ADD, along with various learning disabilities. However, coffee is sometimes used as an alternative treatment for ADD/ADHA symptoms, as caffeine, like other stimulants, actually calms those who suffer from ADD/ADHA , which might explain why Tweek's parents constantly supply him with coffee, believing it will help to calm him down.

In the episode "Gnomes", Tweek tells the other boys that he can never get to sleep, presumably brought on by his excessive consumption of coffee, although he is shown sleeping in the episode "Child Abduction is Not Funny".

Tweek has been shown to have other addictions, besides coffee. In "Quest for Ratings", it is revealed that he fell in with a crowd of kids who were excessively consuming cough syrup.



The parents tend either to oversimplify or to overexaggerate large problems, leading their son to frustrated helplessness when he requires aid or to increased paranoia and fear when he's already obsessing about something. Simply put, whatever Tweek's current abnormal and/or neurotic disposition, his parents serve to aggravate it. Even Eric Cartman seems somewhat concerned about Tweek's condition; when Tweek's newest paranoia takes effect (which was being abducted by strangers) Cartman comments "God, what the hell do his parents do to him?" In "Tweek vs. Craig" Tweek even yells that his parents never tell him anything, that he hates it and that he wants it all to end while his parents ignore him. In addition, his parents regularly joke about selling him into slavery, which only adds to his stress levels.


Despite having a feud with Craig Tucker in "Tweek vs. Craig", Tweek is the character who is the fourth friend in Craig's group most often. Tweek and Craig can be seen standing side by side in various episodes including "Ginger Kids" where they are trapped in a cage together, and in "The Wacky Molestation Adventure", where they are on the same side of the town. Tweek and Craig can also be seen sitting together at school assemblies (one exception being "Canada on Strike"). Later, in the episode "Tweek x Craig", the two started dating. Their relationship is expanded upon in "Put it Down".

After the episode "Gnomes", it can be assumed that Tweek became good friends with the boys, since they choose him above all the other kids to be their fourth friend in the episode "Professor Chaos". In "Bebe's Boobs Destroy Society", when the boys decide they have to make room for Bebe in their group, Kyle and Stan defend Tweek and kick Cartman out instead. Tweek is never kicked out of the group, but he slowly shifts back into Craig's group and leaves the boys behind.

Cartman has nothing against Tweek (even electing to replace Kyle instead of Tweek initially when they wanted to let Bebe in the group in "Bebe's Boobs Destroy Society"), but Tweek seems to dislike Cartman. Presumably because in "Free Hat", Cartman pressured Tweek to make hats and warned him to start trying to shape up or else he would be kicked out of hanging with the boys. Later on in the episode, Kyle, Stan, and Cartman are held hostage by Steven Spielberg and George Lucas - Tweek comes to save them, saying, "All I want are my friends!", Cartman seems touched until Tweek adds, "Except for Cartman, you can keep him."


  • In episode "Gnomes", his parents' coffee shop went out of business because 'Harbucks', a parody of the Starbucks coffee shop chain, opened a shop in South Park, though his father was hired to manage Harbucks.
  • Whenever Tweek is told to do something, he responds by saying, "Aaagh! Way too much pressure!" Tweek seemed to practice fatalism in episode "Free Hat".
  • Tweek was worshiped as a deity in the episode "Simpsons Already Did It", though he wasn't pleased about it.
  • Tweek speaks fluent Mongolian (as do Stan and Cartman) which he puts to use when he talks to the Mongolian warriors he lives with for a short time in "Child Abduction is Not Funny."
  • Tweek is an unlockable character in South Park Let's Go Tower Defense Play. His special ability is him running faster and killing anything he runs into for 5 secs.
  • At, Tweek is ranked #8 in Dan Iverson & Brian Zoromski's "Top 10 South Park Peripheral Characters".
  • Although Tweek rarely speaks in-series, he's been popular with fans since his debut, and became part of the boys' group partially due to fan popularity - there was a movement for Tweek to replace Butters before "Professor Chaos" even aired.
  • According to the Official Site Tweek is one of many characters without a canon birthdate. However, the largely celebrated date by Fandom is August 17th, which has been used as his fanon birthday for several years and is widely accepted.
