A Big Johnny is when a girl is being gang-banged by two men; one penis in her mouth and the other in her vagina. If both men come simultaneously, she then pulls the penises out so that they ejaculate on each other's penises.
I was in a threesome once and we did a Big Johnny. My dick was sticky for three whole days.
Girl 1: “My bff blew Chad the other night and apparently his dick was so big she had a hard time getting it all the way in there”
Girl 2: “ Wow, I wouldn’t have expected Chad to be a Johnny Big Cock”
