The chick you often have lunch with at school. And nope, she's not into you. She just happens to be stuck in the same class as you do.
Barney: I have like 5 lunchtime girlfriends.
Kim: Wtf? Are they blind?
Barney: No they have the same ENG101 as me and the class is off at 12:30. I tried asking them out on weekends, they just told me to f*** off.
