Stemming itself, is the act of anal sex, whilst the "receiver" has chronic, unstoppable diarrhoea, therefore "stemming" the flow. Beware of projectile sprays, and the preparation of plastic sheeting beforehand is a very commonly held practice.

Stemming is something beautiful that occurs between either straight couples, or gay men. It is generally the man, or the "daddy" doing the stemming, as the woman needs an extra attachment to make it work, therefore making it less popular.

Warning: Be conscious of causing an unintentional rose-bud, or pink sock. These events are widely known to be very disconcerting.
Example 1;

Man 1 enters room, and gags/vomits uncontrollably, "Oh my god, this room is vile... and the smell!"

Man 2, "Oh yeah, I brought this filthy bitch back last night and I was stemming her all night... I should probably clean this mess up."

Example 2;

Man 1, "Did I tell about what happened last night? Oh dear... My girlfriend had chronic diarrhoea for hours, and the only thing I could think of to stop it was shoving my cock in her arse!"

Man 2, "Urgh?!? Really?! You stemmed her?"

Man 1, with a big shitty grin on his face, "Yeah, it did surprise her... and she's still cleaning up the mess now. Haha!"

Man 2, "Filthy bitch."
