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!
