Sheen-tastic 

This is when someone is a hot-mess but you don't want them to change b/c you're afraid they will be less entertaining

She is so Sheen-tastic, that I have to invite her to all the parties.

sheentistically--(From charlie sheen and statistics) The increasing probability that a person is going to lose their job due to risky, stupid, crazy behavior.

Guy to friend: Dude, two hour lunches in a bar, coming in late in the morning, smoking a joint in the company parking lot and all this other shit is going to get you fired, for real. Man, sheentistically speaking, you're no more than a month away from losing your show.
