Ejaculating into a partners mouth during oral sex, which takes place in a deep pit style porta potty, similar to the one featured in Slumdog Millionaire. The ejaculator forces his penis into the others mouth during orgasm, and when the person coughs or chokes, they are thrown down into the collection chamber of urine/feces.
Met this chick on spring break in Calcutta, gave her the old Mumbai Mouth blast after she disrespected my clan.
