Shag Nasty 

Someone or something that's so mean that they will fight or act with merciless intent to get want they want or accomplish.

Did see Alan in that fight? Yeah, I don't want to mess with him because he's freaking shag nasty when he gets in a scuffle.

Nice Nasty 

The act of doing one thing and not the other; One who accepts the worse and complains about the best, a backwards thinker, a walking paradox, completing a task and leaving out the most important part, doing something totally backwards, ignoring priorities of major importance and acknowledging the minor.

Justin is Nice Nasty because he didn't wipe his ass but he had the nerve to wash his hands.

He's Nice Nasty because he'd happily eat any kind of feces as long as it had brown sugar on it.

Cumming into a paper bag and then placing it over a female partners head, then lighting said bag on fire.

"I got the Biz Nasty!"

"Yeah, it's in your hair."
