A health nut is a person who is obsessed about his/her health.

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

A sexual act, where instead of cumming on a girl's face, you instead throw tofu at her and scream "Health Nut" at the top of your lungs. Usually done by the vegans.

1) One who spends the majority of their weekly salary on expensive, media promoted, cardboard (liquid or solid state) that tastes like shit. 2) He who LOVES veggie dogs
