Boo, you whore!
From the archives of TiPWiki, the unofficial Duke TIP Wiki
"Boo, you whore!" is a once-disputed quote from the movie Mean Girls starring an actual whore: Lindsay Lohan [Edit: Lindsay Lohan is not a whore, but rather a hot ginger]. Contrary to semi-popular belief, it is not "Boo you, whore!" This confusion was the subject of much debate among some smaller social circles who had nothing better to do with their time... During Term 1 at Duke East '07, a select few TIPsters were known to insert this expletive into speech whenever possible.
This phrase has also been used at other terms of east and even some at Davidson; its usage was reserved for times when one girl wished to go somewhere and her friend would not accompany her.
