Stoner 2: Yes, but IYWIB...

BDIP

"Balls Deep In Pussy" - Pertains to X-Rated photography in which the penis is completely inserted in the woman's vagina, and the man's testicles/scrotal sac is the only thing visible from most angles of the shot.

Guy 1: "What kind of pr0n do you like?"
Guy 2: "MF with plenty of BDIP."
Guy 1: "Dat's koo."
