The shortened form of the word pectoralis major. Guys who take good care of there body and keep a physically active life style tend to get these. They are located in the area where women have there tits. Namely the chest. Girls like a good looking guy with nice pecs. They are usaually very muscular. They look nice too. Wish i had nice pecs.

Dudes who work out,eat healthy foods and take care of themselves get these. They are in the same spot as boobs are on women, but are big and firm. They bounce sometimes if they have a lot of fat in them and they sag just like boobs when the dude gets old or out of shape.
Shawn B. and I like to look at pecs when we go to the beach. Lately though, all we see is pasty white flab and moobs. What happened to our dreams of sexy tanned dudes with an I.Q. over 100?

Used in reference to the muscular breasts of a human male, especially in relation to that of a male bodybuilders who have well developed breast muscles. Pecs can come in many different shapes/sizes and can be very sexually attractive in they eyes of many women (and gay men) .

If you ask me, basically God’s gift to mankind.
