Donut Shop Lady

Donut Shop Lady was a psychopath who targeted Colin Shithead and two of his boyfriends.

History
A psychotic single woman, she owned a donut shop in Madison Avenue. She met Colin and his former boyfriend Luke on Colin's boyfriend, to which she started flirting with Luke and insulting Colin. After Luke proved his love to Colin, Colin insulted the Donut Shop Lady, to which she snapped and murdered Luke. Before she could murder Colin, the police turned up and arrested. She returned later on in Season 5 to which she tried once again to kill Colin and his other boyfriend Luke Edwards. Whilst having a laughing fit, she accidentally stabbed herself. Luke then stabbed her to death.

Trivia

 * It is possible that she appeared in the Season 2 finale as a copy of her character was seen outside her donut shop, but due to a different voice being used, it is unknown if this was actually her.
