A man typically from texas who is very well endowed. The penis tends to be 12 inches long, if not larger! Most men who can be called a "J12" tend to get quite faint when erect due to the penis stealing most of the bodies blood. More fortunately though, a J12 is always a hit with the ladies.
Girl 1: Wow i had sex with Shane last night, who'd of known he was a J12. .
Girl 2: Really? Was it good?
Girl 1: It was massive! But he fainted in the middle.
Girl 2: Oh shame, at least you got some decent cock though.

Get the J12 mug.A ministry based on the "Seven Words of Jesus" at twelve years old... "I must be about my Father's Business." J12, or Jesus |at| Twelve, focues on inspiring kids from 8-12 years of age to have the same attitude of Jesus. J12's motto is "reaching a generation before they need to be rescued."
