A character from the T.V show "South Park". He has very messy blonde hair and supposedly sufferes from A.D.D but his twitching and nervous personality is due to the large amounts of caffeine he consumes. In Series 6, Tweek became the main characters replacement for Kenny, alongside Butters, after he "permeanantly" died at the end of the previous series.
"Tweek's the worst character ever."
"Yeah. Worse than Towelie."
