Visible breasts on a man. Most commonly caused by being overall fat and thus having plenty of fatty tissue in the chest area, resulting in flappy, disgusting, saggy moobs. Can also refer to the breasts on males suffering from gynecomastia, a condition which causes the growth of feminine looking breasts on a biologically male body. Men with gynecomastia typically have fairly small moobs in comparison to men who have moobs caused by fat, but occasionally a more severe case occurs, resulting in gorgeous, large, feminine breasts that many females would envy. Although it is somewhat rare, the word "moobs" may sometimes be used to describe a man's pectoral muscles if they are particularly large and luscious. This use is uncommon due to the negative connotation of "moobs," and the fact that the word brings up unpleasant imagery even when used positively.

Andy decided to get his moobs surgically removed- his gynecomastia was pretty bad. Poor guy. Girl: Damn, look at that pair of moobs! *gropes* So.... firm.... and lucious.... Boy: Er, could you please stop touching my chest like tha- Girl: Shh. Just let it happen. *continues groping*

The words man and boobs fused together. The unusually large amounts of fat stored on the upper chest of a man. Also called a man bosom. Especially disgusting if the male is wearing a very tight shirt and you can see his man titties. It is very humorous when they jiggle around like jelly. Usually seen in overweight people, but can also belong to more average people

Random Chick: Look at the moobs on Vartan! Me: Wow! He's like an F-cup! Vartan: Where does one buy bras? Everyone: Up your ass and around the corner!

Man boobs. Not the kind that like muscley, but are like pyramids on a chest and often require a sports bra or training bra to supress.

That kid needs a bra for those moobs.
