When you get really wasted, crash at someone of the opposite sex's apartment, pee in their bed unknowingly in your sleep, and sketch bounce in the morning. You also may or may have not made out that night. You're not too sure because you blacked out and they chose to sleep on the couch.
"I blacked out last night and my pants and his bed were wet this morning. He's my pee boo"
