Top definition
(n). A very stocky, well cut, well oiled, well tanned male, usually wearing a tank top, often found pressing more than 350 pounds at the gym. Likes to walk in circles, looking himself in the mirror. Quite often does no cardio workout--muscles are purely for SHOW. See Pec Poser.
While at the gym today, I saw this TGG (Testosterone Gym Gorilla) pumping weights, snorting and groaning like a bull on crack having sex.
