Ratchet Party 

The gathering of socially undesirable people for the purpose of drinking, smoking and lewd dancing.

Sarah: Hey Jessica, were you invited to Starr's ratchet party tonight? Jessica: Starr knows not to invite me, I'm not a ratchet, I wouldn't be caught dead shaking my booty in front of others.

Party Ratchet 

A "Party Ratchet" is a person, usually a girl, who gets wild at parties. Basically getting ratchet, but that doesn't mean that they are ratchet in everyday life, Just parties (Ex: Dancing with everyone, getting hype, etc.)

Jessica: Nicole was getting dancing with everyone and gettin hella crazy at the party last night.
Brittney: Well girl, you know she is a Party Ratchet
