frat-nasty 

Dirty, deplorable, disgusting condition; the lack of cleanliness and overabundance of filth often found in a college fraternity house.

"When I saw how much old mac & cheese and other greasy funk was matted on that frat-nasty oven, I literally gagged."

Fratnasty 

When you drink like you're in a fraternity yet you're not because you're either too old or no longer/not in college

Dude, we got so fratnasty at last night's party. I took down a beer bong and shot gunned beers all night.
