A person who plays computer or console games excessively or enjoys programming entirely too much. Gnomes are often characterized by their poor grooming skills, atrocious odor and lack of social skills. Gnomes are rarely seen out of their natural habitat, (bedroom) which known as a gnome hole.
Did you smell the stench comin off that gnome? I wonder when the last time he took a shower was? Or the last time he saw a girl.
