n. Car sales: A person with horrific credit that doesn't pay their bills. They may get financed but if they are, it will be at an incredibly high interest rate. These creatures usually come in some beat up dirty trade-ins that they have often negative equity issues with.
Man, I cannot believe we got that Rat financed on the deal! I guess it helped that he had $5000.00 down!

Acronym for roll and tug. The art of self pleasure when your hookup decides not to give it up. Waiting until your bed mate is asleep is at your discretion.
Dude, she didn't give it up. But that's OK. Did a little RAT instead.

Girl: "I'm not ready to have sex with you."
Dude: "That's OK, I'll just RAT and pass out."
