fake a piss 

In the context of office and corporate culture, when two men enter a restroom and have to shit, one enters a stall, and the other gets shy and "fakes a piss", opting instead to pretend to urinate and return later for another anonymous attempt at defecating. One can also "fake a piss" if there are too many people shitting, and using a stall will entail crapping too close to other people. It can also be used if someone sees you enter the bathroom before you can sneak into a stall.

"Man, I had to shit real bad, but the managing partner saw me in the bathroom, so I had to fake a piss".

Piss-up 

A drinking session. A booze up.

Proverbially, the thing that a particular bad organiser couldn't organise, even if by pure dumb luck he happened to find himself in the place where beer is produced.

Another government IT project's gone pear shaped, seems EDS really couldn't organise a piss-up in a brewery.

Fat piss 

When you've been holding your pee for literally more than 3 hours so when you finally do release your pee, you don't have to push it out, it just flows.

Dude, I was at that party all night, and when I got home, I had to take a fat piss.
