aj 

acting jagoff- a person temporarily put in charge while the boss is away.
double slam, one to the boss and one to the fill-in who let power go to his head

I can't wait till sarge gets back. They made Sammy the aj and now he takes everything like it's legit.

AJ 

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.
