when you tell someone who keeps pursuing you and trying to hit on you to back the fuck off or to cut the crap because you're just not interested

In prison, an inmate is asked to "drop the chalupa" which means to squad down, lean forward enough for the guard to see their asshole, then cough. This is how guards check for things shoved up the ass.
Hey offender, why are you acting weird? Get out of them and drop the chalupa!
