A person (usually male) who most appreciates the breasts of a woman over other parts such as the legs or butt, sometimes to the point of obsession.
Male 1: DAMN! Look at the ass on that girl! Tell me you wouldn't tap that!
Male 2: Mmm, I dunno. I'm more of a boob man, and she's definitely lacking up top.

what often happens to men who workout with barbells, dumbbells, free weights, nautilus, et al over long periods of time. The testosterone enzyme increases with the added muscle mass they develop, but so do their estrogen levels to keep a proper balance, such that they develop breasts (and buttocks) akin to females who produce this enzyme naturally.
Tina : I would date Bruce, but he has such noticeable man boobs from all those years of working out. And now they sag somewhat - gross !
Me : sez you ! You're as old as he is, and your boobs are beginning to sag, too.
Tina : yes, but mine are natural - and I wear a bra.

Me : well, buy him a bra, too and when you both are having sex, just make sure he wears it .

You morons are all fucking stupid. Gynecomastia comes in two forms, one is caused by obesity where sometimes the fat stores in the chest area, creating breasts in fat men. The other one is caused by a hormone imbalance in men that causes breast tissue to form underneath the nipple area, so even if you are skinny, you can have big boobs. Don't feel bad if you have it, as there is a cure. Most plastic surgeons generally charge $1000-$5000 dollars to do a glandular excision and/or liposcution in that area, removing them.
Many celebrities have it too, like Simon Cowell, for example.
Don't let anybody push you down for having man boobs. Beat their asses or something for twisting your nipples, that's the only way they learn.
