Man boobs is when the man is just so fat, you can make out two titty shape on his chest. This is extremely common throughout the US, where recent statistics shows that a shocking 98% of US male (ranging from fetus to corpse, only in the US of course) actually have man boobs.

The term given, by a recent scholar, is "moobs".
Moobs cannot be cured, as it is in all American male's gene to be fat and ridiculous, I am sorry, I cannot help you.

Scientist have speculated that in the future, because so many man in the US have moobs, 98% of the male offspring will be transformed into half male half female, fat, ugly, but with huge titties.
