A gathering of 3+ men that stand in a circle naked each one with their weiners up anothers butthole all pumping back and forth as if having sex.

Get the Penguin Circlemug. A large group of men (or hermaphrodites, women with strapons, etc.) anally penetrating each other, each bending slightly in one direction, resulting in a full loop.
This can be done either horizontally or vertically, however while vertically is more difficult to pull off, it is also far more hardcore.

Get the Circle of Lovemug. Much like the ever-popular circle jerk, the slam circle involves a group of young males assembled in ring formation. They then reach to their immediate right, and proceed to whack off the guy next to them. In the middle of the ring, there is a small bucket that collects all the semen. The last to ejaculate (loser) must drink the contents of said bucket.
Frank: Hey im going over to Tommy's frat tonight, want to come?
Joe: No way man! All they do there is start Slam Circles!
Frank: You just don't want to go because you always lose!
