Vapor vaulting is the act of pressing one's anus to another's, particularly after coitus, when the undercarriages are at their moistest. A gaseous deposit is then made into the receiving butthole.
Yeah, man, we were wiped out, but we were sweaty, so I thought to myself, "Why not? I'm gonna try vapor vaulting you."
