this term is used to describe individuals with unusually large and awkward forehead regions. See FUGLY This is more commonly used to describe women foreheads rather then mens, since men commonly recede at the hairline. Fiveheads tend to be more commonly found on Asian and African Americans. Basically one big forehead.
"Sarah's fivehead was out of control today; dripping with sweat and splotchy like you wouldn't believe."
