When one guy pops another guy's turd in his mouth, then the other guy does the same with one from the first guy, and they do a spit and catch juggling thing until one of them misses it and has to wear a used condom round his neck for the rest of the week. Very popular in Iowa.
"Dude, I was playing Chocolate Egg Tennis last night with Steve, and my fucking mom rang! My boss did not like seeing me turn up at work this morning with a dirty bag of jizz dangling off my St Christopher. I think I'm gonna get fired."
