Sexual act involving the connection of three human beings via face to bung hole. Much like the human centipede yet one decerning factor, the legs and arms of the particpants must be cut off or missing prior. In most cases the spines are broken to simulate proper worm moving mechanisms.
Man last night sucked I got stuck as the caboose in our human worm and now require prosthetic legs and arms, she was not worth it.
