The act involves two men and a straw. The straw is inserted inside one of the men's asses until the rectum is reached. The other male then proceeds to suck hard on the straw until fecal matter is absorbed up and through the straw. The poo particles are referred to as the shrimp.
I'm hungry and the only cure for it is butthole shrimping.

Not only are those guys flaming faggots, but they also love to shrimp each others buttholes.

I got a straw and a butthole. You know what to do. Start shrimping.
