A person whose marijuana stash consists totally of THC infused edible gummies of various strengths and flavors. A gumhead does not smoke weed, inhale vapors, or use sublingual cannabis oils.
I saw an old High School gumhead friend the other day. He still carries gummies in his vest pocket!
A person, typically a male, who is obsessed with going to the gym or working out. This person will spend hours upon hours bulking up, pausing only for protein shakes or supplement use. Gymheads often go after their own breed and tend to spend most of their time with those who love the workout grind as much as they do.
"Have you seen that guy at the gym?"
"Yeah, he's always there; that's where he spends all his time. He's a total gymhead."
A Gumhead means a person with a scar on their head. Usually the forehead.
It is refered to as 'Gum' head due to the scar tissue looking it like a gum.
Also known as a DFontanahead
