When you have a date in mind but don't want to commit so you just say "Swoon" and "Wannanow".
Mostly a Non sequitur, it may be used also as a threat, a question, and a noun.
Made popular by MMA fighters Wanderlei Silva and Chael Sonnen
Note: most applicable when you don't wanna be friends
Chael: I just wanna know the date
Wanderlei: WANNANOW?!
