look up any word, like dirty sanchez:
 
1.
A beard that is so small and pitiful that you can see the skin through it. Flesh beards are very common in people that are to young to grow facial hair, but still try, thinking it makes them look cool by trying to grow a beard.
Matt: Robert, I just hit puberty!

Robert: Ugh, yeah and you have a flesh beard.

Matt: Shut up! I do not!

Robert: Yeah, you do. It makes you look like a dick.
