A fork of Rural Dictionary
A man or a woman, who is submissive by nature. The buttboy (unisex) will always be the weaker individual in a relationship. The buttboy will bend over and present themselves to the dom regularly, because a buttboy lives to be a spineless individual. Anyone who is a whiner, or an overly sensitive person can be considered a buttboy as well, it is not necessarily sexual.
Camille and I were trying to figure out who the buttboy in the relationship was, turns out she's the buttboy!
