hibble dibble.

take a cork, some matches and a shitload of booze. get slightly plastered beforehand then take turns saying the hibble dibble rhyme (which i can't remember at the moment). if you laugh or get any words wrong a charred cork is stamped on your forehead and a chosen amount of a particular beverage is necked. great laugh, especially when you wake up the day after with a load of black smudges on your head.
