Flip

When someone who is not homosexual says they are for one day in order to try it or takes part in sexual actions with the same sex to try it. Usually someone who flips regularily is actuall homosexual but finds it difficult to admit it so they flip.

Female one: I love that song by Katy Perry "I kissed a girl"
Friend of Female expiramenting: Yeah, me too. I love it. Want to kiss just to try it.
Female one: Totes, it's just a flip so it won't mean anything.
*smooching noises ensue...and it usually does prove something...
