An expression taken from "
buy now, pay later." This refers to the (often
untrue)
assumption that bisexual people are going through a phase and will eventually come out as gay. It is usually considered offensive.
guy:
you're gay, right?
me: I'm
bi.
guy: bi now, gay later
or
guy: What was she doing with another woman? I thought she had
a boyfriend.
girl: she's on the bi now gay later plan.
