BUE
an acronym that stands for "bust upon entry" and describes the immediate ejaculation that occurs the first time you bang a total slam piece. more prone to happening on boats in the islands. a BUE can occur for several reasons, which include: banging a girl after a little too much foreplay, triumphantly banging a girl you've been trying to bang for a really long time, banging a girl after a long dry spell, banging an unbelievably hot girl, banging a girl for the first time without a condom on, banging while thinking too much about how you're presently banging, or really just any time you pull a BWS (banging while sober)
"dude i paid $400 to bang that stripper but it was a total BUE. what a waste of money"
