look up any word, like bae:
Going to prom with a "promstitute" only for the guarantee of after prom activities.
I have decided to not partake in promstitution and instead hang out with my friends.

Paying upwards of $100 for prom and prom-related expenses while remaining mostly interested in the horny, sex-crazed activities that follow.
%: Dude, why are you shelling out for prom? Do you even have a date?
&: Naww, it's really just promstitution.

The naked man at post-prom was clearly a promstitute.
