The phallic shaped bulge visible to the naked eye, through a man's jeans. Usually hanging to the left or right. Jean cock is often very deceiving, as it usually appears bigger than what is actually underneath the jeans.
"Hey Nicole, did you see that guy's jean cock? He looks like he is packing some heat!"
"No, Danielle. I just fucked that guy 2 weeks ago. Such a pencil dick, I wanted to write my name with it. Jean cock strikes again..."

Jeans cock is extremely long, black, hairy, wide, thick, and furry. It extends from Jean Martin all the way to the planet of Pluto. On its way to pluto, it goes through Uranus (HAR!). Jeans cock is also extremely black, so watch out for it sneaking up on you in the middle of the night as it can easily disguise itself as the sky.
Also, watch out for jeans cock on black friday. oooooooooosmf!

Sized-down skinny jeans can become cock jeans. "That guy with the cock jeans is advertising only how small he is."
