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.

"I've just done a trouser sneeze lads"

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"
