ratchet 

Something undesirable, ghetto, or a hot ass mess in general. Nobody wants to be around someone that's ratchet. They tend to like surfing and videotaping jokes that aren't funny.

Robert Meadows is ratchet, he's a hot ass mess.

Ratchet 

Someone or something hella ghetto. Educated people say wretched but with a ghetto people say ratchet. Tomato/tomatoe, wretched/ratchet.

Ratchets never win spelling bees.

My friends Norma and Michael are straight ratchets. They communicate by twerking.

Ratchet 

A cold, heartless, ghetto-ass bitch with a big ole bootie. A chick who won't let you even beat off or fuck a whore. Based on the character Nurse Ratchet from One Flew Over the Cuckoo's Nest.

When nurse ratchet won't let McMurphy fuck his prostitute girlfriend, she was being real ratchet.
