Lagerita
A Margarita cocktail for tough guys. Lager mixed in with the tequila and the Cointreau is omitted. Friends in Sydney tried it at a bar on Manly beach but rumour has it that it originated in the UK (not surprisingly!)
Latchico
A corruption of the Irish for "half a hat", or more explicitly half a penis. Usually used in reference to wide boys, cute hoors or dodgy geezers.
Ur some latchico, boy...
