A bi sexual bitch. A guy/girl (mostly girls) that is bi sexual and takes advantage of vunerable people that are testing out their own sexuality.
lola's such a BI-tch, she told me she liked me after i told her i was BI curious, but right after we got with each other, she dicked me over, and hasn't talked to me since.
