Butters
The following has been provided by Tonya.
Leopold "Butters" Stotch (voiced by Matt Stone) is a fictional character in the animated television series South Park; his nickname is a play on the word butterscotch. Butters has a large tuft of blond hair on top of his head, and wears an aquamarine jacket with green pants. His birthday is on September 11. Butters speaks with a distinctive Southern accent with a wholesome manner. The character is loosely based on South Park director of animation Eric Stough, who Parker and Stone regarded as a "goody-goody" because of his reluctance to offend.
The creators have said in multiple DVD commentaries that Butters is one of their "top 3 favorite characters".
Butters is described by fans as having a warm and friendly personality. He is naive for his age and his innocence is often a target for abuse. Butters is very submissive and gives into peer pressure very easily.
