Get the piss-ups mug.
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

A 'piss up' is British slang for a drinking session, so if you couldn't organise a piss up in a brewery, you really suck at organising things.
"Im getting married in a few months but I'm going to leave it to Steve to organise the reception"

"Fuck that! Steve couldn't organise a piss up in a brewery... I'll do it"
