twin-ender

The act of passing gas from both one's mouth and anus simultaneously, usually caused by unexpectedly sneezing while trying to hold in a fart. Due to the great stress placed on the body while sneezing, the accompanying fart may be much louder and violent than a regular fart and often causes a small amount of anal pain.

This can be especially embarrassing in public places if the sound of the sneeze does not cover the sound of the fart.

On rare occasions, you may be unfortunate enough to encounter the 'twin-ender with sauce'. This occurs when the fart is accompanied by the expulsion of faecal matter (commonly known as a shart.)

Twin-Twin Transfusion

A sex act in which, the male(s), while fucking twin females, cum into the mouth of one twin and she then spits that load into the mouth of the other twin.

A play on the actual condition in which during a twin pregnancy, arterial blood from donor twin passes through the placenta into vein of recipient twin. Essentially the donor twin gets less blood and the recipient twin gets more.

Man I had a great time with those twins yesterday. They even performed a twin-twin transfusion.
