A Moriarty
Glasgow slang for a party. Usually happens when you buy a 'cargo', which is just a fancy way of saying you're buying Buckfast Tonic Wine, and then you get really drunk.
'We had a party. Then we had a cargo. Then we had a problem.'
'Cargo = Buckfast = party = hangover = life.'
'She came to the party. She bought a cargo. She became the cargo.'
