What is Piss-up?
1.
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 :)
2.
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.
