When a bunch of guys (maybe girls wearing strap-on dildos) insert their dicks into the anus of the next person in line. Works like an Armenian Conveyer Belt, except the chain in completed when the last person of the chain puts their dick or strap-on into the first person's anus, thus completing the circular fuck chain. Similar to an Armenian Conveyer Belt except circular in shape. Typically a stand in referee calls out the stroke timing for each synchronized group thrust. This referee typically uses a megaphone, and metronome, and wears a leprechaun outfit.
I'm going back to the party to partake in an airport baggage claim with some old high school friends.
