S/PDIF 

Stands for "Several Pretzel Dicks In Formation" When four men lie naked, intertwined in a pretzel like formation, causing their penises to be 4 points of a square. They are then given handjobs at the same time, with the giver of the handjobs rotating around the square, supplying 1 stroke per penis. How climax is handled depends on he/she performing the act. That is considered one's unique artistic interpretation of the S/PDIF.

Dude kinda got hammered at the club last night. I ended up locked up in a S/PDIF with some random dudes I don't know. Girl jacking us off had soft hands though. I still had a good time."
