Often a brilliant source of cme down fun.
Go for an event like Hardcore Heaven - One Step Beyond (made that one up but a good example) that you've never been to, find a picture of someone who looks a bit rough (boy or girl, but girls tend to work better) and accuse them of 'copping off' with with your boy / girl friend OR being a bit of a rat face and you can guarantee some fun - lay the bait and enjoy.
