the act of looking like a ratchet, messy, just plain gross. For example when someone gets drunk and starts acting trashy, or in many cases where a girl never cleans herself up and is always looking nasty

A douchebag who cheats on his woman and falls in love with their best friends. Also may be a person who takes his mother's clothes off in the middle of the night and beats off on her all night long.

Also likes cat porn.
