Bog Beers

The art of sneaking in your own drinks to a venue to avoid paying their extortionate prices then consuming them in the comfort of a cubicle.

Adam– “Where’s Joseph and Pete?”
Dan – “They’ve just gone for a few bog beers”
Adam – “Good idea, I’ll join them”

Pete – “It’s eight quid a pint at Adam’s wedding reception tonight." "How many bog beers are you bringing?"
Joseph - "Fucking loads”
