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!

A unique sexual activity requiring advance preparation and a girl you never want to see again. Before sex, get a condom and fill it with every bodily excrement imaginable. (i.e. shit, piss, vomit, snot, sweat, cum, saliva, and that diarrhea liquid shit). Tie off the condom like a water baloon, and stash it somewhere near the bed where it can be discreetly reached. During sex, change to doggie style, and just as you cum, break the condom over her fucking head!
"Hey, what happened to that chick you took home last night? You gonna see her again?"

"Naw, I dropped the chalupa, so she won't be coming around again."

"Oh, cool. Well, then can I have her number?"
