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).

Smack Ass
To grovel to one's superior with no regard to dignity or shame. One who performs the act of groveling.
Hey Bill, look at Bob. He's always in the boss' office smacking ass. He's too lazy to get that promotion.
Im talking to you, smack ass. Didn't I tell you to bring my coffee in here by 8:00 a.m.? It is now 8:10 and I don't see my cup on my desk.
