wannagooutwithme? 

Question asked by nervous males in the presence of a girl they really like, regardless of whether she is a slut or not. Commonly said at lightning speed and often in a very quiet voice. Success rate of around 2 in 3, as many girls take pity on his nervousness and foolishly say yes when they don't mean it, which usually leads to heartbreak on the male's part when she sleeps with someone else the week later.

Seb: thing is Dais, I really like you so.. wannagooutwithme?
Daisy: um, ok.
