Bum Wee 

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.

Very Dark Brown Bum Wee = Guiness

Bum Wee 

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.

He had bum wee and lost his lunch

Bum-Wee 

A term used to describe a male urinating while standing up but opting to lower both their trousers/shorts and underwear, fully exposing their bum in the process, rather than simply unzipping or lowering the front portion of their clothing for urination convenience.

That man is at least 40, can you believe he's doing a Bum-Wee in public

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.
