Two licks and a promise

Definition:

When a girl is drunk and she says she’s going to give you a blowjob, but all you get is two licks and a promise.

Exemplification of usage:

Him: I was sexually frustrated in that relationship. She didn’t like giving head, and she was drunk all the time, so all I got was two licks and a promise.
