piss up in a brewery 

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"
