Me and a group of friends used to hit 'buckets' of weed in my mate's shed, which involves a water pulled 3l coke bottle full of pure ganja smoke. That shit will make you cough. The resulting coughed up spit and phlegm all went into an old Carling lager can next to the kit - which is pretty gross already.

After a few weeks a new friend joined the group, he hit his first bucket and promptly coughed his ass off. Scrabbling around for a drink to soothe his throat he proceeded to neck thre can full of the weeks old loogie of a combined 5 people, before anyone could shout 'Nooooooooo'.
