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.

Piss-up 

More commonly used in Australia; basically a social gathering or full-blown party intentionally to get drunk. Commonly associated with pisswrecked, pissed, wreckless, drunken, wrecked, fucked.

In the holidays, there was a massive-arse piss-up to celebrate no school. 'Twas well-sick :)

piss up

A term for getting drunk. Generally a term used by under 18s who think they're cool on facebook. Photos are taken at the event, in which the teens are holding large cans of energy drinks, carefully positioned to look like a can of beer.

Person 1: we better stock up on red bull for our piss up, so we can look cool on facebook

Person 2: good idea, make sure you turn round the cans in the photos so it looks like we're actually getting drunk
