Shitting on a pickle and then proceeding to have some form of sexual penetration. As soon as you cum you start farting. Then everyone gets on the floor and does the dinosaur.
Derived from a story my dad told me from when he was in the navy during the Vietnam War. For some reason a man frequently bragged about his "cherry ass." He bragged so much that one day his coworkers shoved a pickle in his ass. The man squatted, pooped out the pickle, and cried. From then on, he was called "Pickles."
