zipperback

A type of hat that gives the rear of the hat a much cleaner look. Instead of being adjusted by a strap or snap, it is adjusted with a zipper. The zipper may very well be one of man-kinds greatest inventions next to duct tape. The zipper may be easily adjusted for personal comfort. Overall, better than strap and snap backs.

jesus zipper

Jesus Zipper, the line of skin that goes from the base of your man stick (penis) straight down and around your pill pouch (scrotum) all the way to your brown star (anus).

The term Jesus Zipper was coined by AJ Styles after a mishap in the ring that left him straddling the ropes in an unceremonious fashion. During an interview he said "I landed right on my Jesus Zipper."

Zimmerman Zipper

An emergency release mechanism for your pants incase your penis gets zipped up into it when zipping up your pants.

After i was done last night i was putting on my pants when i came inches from slicing open my urethra. Thankfully i was wearing my zimmerman zipper. I pulled my emergency rip cord and that situation was narrowly avoided.
