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 round Emma's face is?!'
'Yeah, massivepie face.'
Verb.
To shove someone forcefully, but by the face as opposed to the chest or shoulders. Derived from the cartoon action of smashing a pie in someone's face.
