igabuf 

stands for "i'm going to barf in your face"
it can be used as a nickname for when an obnoxious over- zealous girl makes it clear that she wants your boyfriend when she knows about you, but chooses to not admit it to herself, ignoring the relationship and persuing him anyways.

Jen: Did IGABUF call your boyfriend today?
Shannon: No, but she wrote on his facebook wall... AGAIN!
