The most extreme form of mental.
- When you're able to clearly identify someone who is mental through the natural look on their face, despite them acting in an otherwise rational and sane manner.
- Ideal as an insult; typically a step up from mental or mental in the head, but can also be used as a description of how someone looks. For example; if they genuinely look as though they are about to massacre an orphanage.
- Look, if he's such a good friend, then why can't you just be honest with him?
- Honest? Are you mental in the face? Imagine how that would look.

Thomas Leone is mental in the face. But if you ever say this to his mental face, he will roundhouse you in the prick.

Get the Mental In The Face mug.
A face usually used by normal people to look like mentals. Involves tilting the head forward, putting an angry look on your face and jutting out of the jaw. Usually best executed by people with braces on. Holding up your fist and shaking it is another good addition to complete the mental look.
me: LOOK! LOOK! LOOK!
