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."

Relationship Assuring Text. RAT's are SMS messages sent to convey approval of or delight in a previous social encounter with an individual of undefined relationship status with the sender. A RAT is most commonly employed after a first date where one or both parties are unsure about the perceived success of the other party. Such dates are often seen as "Awkward dates" by third parties. An exchange of RAT's sent the evening after a first date almost ensure a second date, effectively breaking the ice for more casual conversation.

The effectiveness of "Morning RAT's" (RAT's sent the morning after a first date) are hotly debated because they are believed by some to close the deal, but can also be seen as a red flag.
Guy 1: I wasn't sure how dinner with Daniele went, but she sent me this text afterward: "I had so much fun at dinner! Thanks so much!!! :)"

Guy 2: Dude! with a RAT like that, you're golden!

A person who exposes another person's wrongdoings for reasons other than moral outrage or to seek justice. Usually for personal gain, to avoid trouble themselves, or out of jealousy.

The word is sometimes misused by highly immoral people to describe all people who provide incriminating evidence against other people, simply because they dislike the idea of being exposed, and want to associate a negative word with people who expose immorality.
Grant exposed the other members of his gang so the cops would reduce his sentence. He's a rat.
