Face to Pan

The act of tripping/frying so hard on acid that you're essentially frying your face to a pan...

That acid last night was so bomb! I fried face to pan!

You look like you've been hit in the face with a frying pan.

A flat faced person with no defining features. Big round flat face. Painful looking smile. Unattractive profile. Great insult for a low quality human.

You are so ugly, you look like you've been hit in the face with a frying pan.
