An expression often used by ravers to describe the way one is feeling and or looking after the excess consumption of drugs. Usually ecstasy and other party orientated substances.
" Yeah mate, I've had a couple of those pink E's and a fat line of K......I'm fucking pie faced"
The name given to the facial area of a person who has an abnormally large and round face. As implied in the name, the circular face will resemble a pie, or a perfect circle drawn carefully with a compass in maths. A person with a pie face is likely to be mocked incessantly by 'friends', and subsequently may find it hard to talk to people without them thinking they are talking to a floating pastry.
'Good heavens, have you seen how roundEmma's face is?!'
'Yeah, massive pie face.'
