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.

Get the Bum Weesmug. An illness / infliction often found to affect 18 - 30 yr olds the morning after a big night out.
The bum wee is consistency of water, approximate density of 1001 kg/m3 and can be coloured various different shades of brown (linked to what alcohol has been consumed the night before - for example - Very Dark Brown = Guiness)
It can cause some "irritation" of the bottom, but this will subside once the bum wee ceases.

Get the Bum Weemug. 
Based on an anal explosion during the civil war in 1386, Capt. Donald Rumkinson of the 3rd dragoons lost ten of his best infantry men to bum wee when they were caught short and shot by the enemy whilst their rear ends were exposed. It is basically pissing from the arse and can strike at anytime, but is usual after a heavy night of booze, boot and greasy food.
