a mildly amusing word to call someone so you will have their attention.
amie: hey slutnugget, get yer ass over here.
tom: i love when you talk dirty to me.
It started as a nickname for my best friend, who is REALLY popular with the girls, but became a household scapegoat.
Whenever something goes wrong that you don't want to cop to, blame it on slutnugget.
*dish breaks* Slutnugget did it!
*friend annoys you* Shut up, Slutnugget.
