A deplorable sex act originated in Charleston, SC by meth addicted trailer trash in which one person deposits feces into the anus of another person. The method through which this act is achieved varies by region. The North Charleston Charley Town Swap is the most unpleasant, usually requiring tools to open the anal cavity of person A while person B squats over them like they're a dirty truck stop toilet seat and dumps into them at their leisure.

When two police cars park side-by-side in opposite directions with their windows down so they can talk.
I totally thought those cops were going to pull me over, but luckily they were just having a donut swap.

When a bald police officer gently handles your meats in exchange for other meats meant for your mouth.
“Officer Swallace whipped his meat out and we had no choice but to engage in the ole Fellsmere Wiener Swap. I’ve never had a more firm, moist wiener between my buns”
