A move made in a threesome when the guy tapes the girls' legs together playing out his fantasy of a three legged race. then uses the rest of the tape roll to shove up his asswhole because it is sexually stimulating for him. He ends up with the role stuck in his ass while the girls' heads bashed into each other on their three legged race and knocked them unconscious so now the guy is a murder suspect and goes to jail with the tape roll still stuck up his ass.
