wee bum

When you eat something so rotten that your body wants to get rid of what you consumed so fast that it bypasses every part of the digestive system and heads straight for the exit.

friend:Oh god what is that stench?
me:Sorry mate, at a late night California Burrito @ Filiberto's (aka Fili-squirt-o's) and gave me a bad case of wee bum.
