Typically males that spend more time working on their muscles to compensate the fact that they do not have big enough personalities to attract women.
These males often pluck their eyebrows, get fake tan, have sleeve tattoos and spend more time on their own appearance and looking in the mirror than most girls.
"this guy tried to hit on me but he was such a Gympanzee"
A young, often metrosexual, male homosapien. Can be distinguished from other members of the species by their lack of shirt in profile pictures, their fondness for drop neck vests, and the amount of time they spend looking at other mens bodies in gyms. Not necessarily homosexual, but not smart enough to realise that by posting half-naked pictures of themselves online that it's mostly men looking at them. Can often be found strutting around populated areas at weekends wearing shirts two sizes too small for them, showing off their guns. Act tough, but when actually involved in physical altercations can be heard making a distinctive "Not the face" noise. Often become a gympanzee as a result of being a wimpy adolescent.
