look up any word, like fap:
 
1.
Vax
To have sex. Originated from a scene in Van Wilder in which Kal Penn says "vax it, vax it". It sounds the best when said exactly how Kal Penn says it in the movie. Just like the word "fuck" it can also be used in various situations where it does not necessarily have to do with having sex.

Lets go to the club and vax!
