1 definition by one of yo momma's boyfriends
A person who constantly annoys people either for the fun of it or he/she is just completely stupid knowing that he/she will obviously get in trouble with a painful punishment (Hitting, yelling, scolding, grounding, etc).
"Could you get that little Smack-Ass off of my lawn?", "Keep that Smack-Ass away from me!", "You Smack-Asses are going to get it now!"
