Jack Bob Livingston

Urban legend creature, said to take on the form of a rabbit, from the magical land of shroom. The only known proof of Jack Bob Livingston's existence is by playing side B of certain 70's rock band albums backwards on a record player. The record is played in reverse until an eerie screeching rabbit can be heard crying "shroomsss".

"Dude, are we trippin our faces off, or did we just hear Jack Bob Livingston?!"

The Jack-Tepper Cut

A style of hair cut where a long mullet is grown out while the tips of the hair curl up at the end. This haircut is predominantly worn by hockey players who also associate with the clique "fuckbois". Gel is often used to assist the curling of the hair.

Cobly's friends made fun of him for having the Jack-Tepper cut; his hair looked like it wrapped itself around a helmet and became a squid.

Post-jack courage

(n.) Similar to "Liquid courage."

After just having masturbated, the feeling of being able to call up that girl you've always wanted to go out with but were too chicken-shit to do it before. Often short lived.

I finally called Emily last night while I was still hyped on post-jack courage!
