During an orgasm a girl will spontaneously poop and fart at the same time. A very rare type of orgasm.

A shartgasm: masturbating before you have diarrhea. Cumming and making the first wet push at the same time.
I sat down an hour after indian food and decided to jerk off. I came just as the first salvo came out- what a shartgasm!!
