trouser sneeze

The eruption smelly gas coming out of the anus. Sometimes it makes a noise sometimes it doesn't. The one that makes a noise is known as a trouser sneeze. You have to be careful not to follow through. See fart, trump and air biscuit.

Trouser Sneeze

Ejaculation in one's own pants, literally. Metaphorically used as an expression of ecstatic excitement.

"Did you just snow your dacks?"
"You bet I did! I just had a massive trouser sneeze"
