look up any word, like yeet:
During an orgy, the sexipede is the phase in which each person is connected in any way to another, forming a centipede with sexual connections.
Guy 1: "Hey dude, last night I got to be part of an orgy... It was unbelievable! We were all connected one another!!"

Guy 2: "What!?! You were in a sexipede!?! That's sick!"
