1.
A man who thinks it is attractive to be skinny and lacking in muscle mass or any outward physical appearance of masculinity. The most amusing example being young, metrosexual males who weigh 120-140 pound and go to the gym to "tone" and "get cut", but fear "getting too big."
Last night when I wanted to squat there was some manorexic kid pumping out 20 rep sets of frat curls in the rack with the bar plus 10 pounds. When I told him to move so I could squat, he told me he never did those because they are bad your your knees and he was afraid the huge testosterone and GH release would cause him to gain weight.
