concert girlfriend
A girlfriend that acts really lame at events that her boyfriend brings her to. (Concerts, of course, are the most common event for this to occur at).
(At a Parkway Drive concert):
Lisa: Can we leave early? All this loud music is giving me a migraine and people keep bumping into me.
Tom: Ah, quit being such a concert girlfriend.
