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.
My best friend Nick, took off his shirt and showed off his pecs. The girls love him.

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?
