Backout Baker 

Any girl who has built a reputation for saying she will do things with the guys, then decides, at the last minute, not to.

Mike: Dude let's go and get our tattoos!
TJ: Okay, man, let's go! Wake up Ashley!
Ashley: I'm not getting it anymore...
Mike: Man what a Backout Baker

blackout backout 

When you are so drunk and hate everyone at a party that the only option is to go home and drink alone. Essentially getting blackout, realizing other people suck, and then backing out of having to hang with them.

DBag 1: Dude where did Michelle go?
DBag2: I don't think she likes any of the options here, so she did a blackout backout.
