Abbreviation for Average Joe. Most comonly a male who cares more about having sex then he does about his girlfriend. It can also be used to describe Females, and it can also be used as other parts of speech.
If you were AJ, you would have taken off my shirt by now.
It is not exactly AJ to kiss after 4 months.
Oh my god, you AJed her !!!

AJ stands for arm jelly. The fat on the back of many a girl's (or guy's) arm that HURTS LIKE A BITCH when it gets pinched.

Working on building tricep muscles will often eliminate this.
When Alicia pinched my AJ today, tears welled up in my eyes.

That girl's got a LOT of AJ.
