A pork shoulder is more commonly known as a large seasoned roast typical of Hispanic cultures. However, internet subcultures have recently begun to use the phrase to describe a technique of sexual nature. Typically involving a man, his wife/girlfriend, and possibly her sister. The nature of the move is a mystery, but the humor involved and the dumb looks you will get are well worth it.

Get the Pork Shoulder mug.
A sexual act wherein one partner, after application of copious amounts of lubrication to their armpit/s, keeps their arm to their side while a male partner porks their armpit. This act, while typically performed from backside, can be exectued as a front side maneuver and the resulting explosion may be relieved in the Porker's face.
