Jack Johnson

Jack Johnson is a legendary boxer who fought not only opponents in the ring but also racial bigatry prominent in the United States in the early 20th century. He could not get white opponents to fight him so he would follow them around the world and taunt them. He died in a car accident. There is also a semi-talented singer who happens to share his name.

Jack Johnson would have fucked Muhammud Ali up!

window jack

The act of masturbation while resting your chin on a windows seal and watching your neighbor lay out in the sun. All the while, dressed in nothing but a 1985 pair of terry cloth running shorts cut so short that simply sitting on the bed exposes a hint of your grundel and nut bag.

"Man, my mom caught my brother window jacking the other day. He must have been mesmerized by her bikini spider."

"Dude that's tore."

"Yeah, he couldn't put it away fast enough because he was giving himself the shocker at the same time."
