Aj
Believe it or not, it can be a girl's name! Girls named Aj typically love their names, even though they may be asked if it's a boy's name or if it stands for 'apple juice'. Sometimes they might be dubbed 'Ajax' like the detergent but that isn't their fault.

They are friendly, impatient but not demanding. They can be a little bit stubborn, but they aren't selfish and if you're their friend or someone they care deeply about they will teach themselves to be patient with you. They have a hard time releasing past incidents, and letting go of grudges can be a struggle. They make great friends, and although they are usually low-key they can get crazy, usually at parties or on summer nights.

They often have small facial features, and are small and pretty. They have cute expressions like scrunching their nose.
"Do you remember Aj/Ajax?"

"Fuck yeah, she's adorable."

AJ is a nickname for a male. Usually short for first and middle names. AJ's are ladies men and get a lot of girls. They are very flirty guys, but when they get into relationships they become loyal and tend to let their significant other control them or whip them around. VERY good in bed, and also a very good friend.

Aj
A man who is a total badass. Most likely a marine or some other bad ass profession, such as porn star, elected official, super-athlete or even C.E.O. of your mom. Disclaimer: Will fornicate with any friends hot mom with out regret. An Aj is a cold blooded ladies man with the future in his eyes and fire spewing from his mouth.
An Aj usually makes good money, certainly more than you, yet your not exactly sure how. An enigma will spontaneously combust if ever to come into contact with an Aj.
An Aj can be found in Public places such as cities, towns, or American territories. An Aj can also be found in the isolation of the deep wild where he may be pondering ponderous thoughts of the very existence of time and space which would cause lesser men's heads to implode in the manner of a rather disturbing sucking sound. 
I digress explaining an Aj any further would simply take away from the only pleasure you will know for the next 20 minutes. The basking in of the the thought of the very essence that is an Aj.
Girl 1: Woah, check out that Aj over there.
Girl 2: I think he looked at you!
Girl 1: Well that would explain wy my bra's off, panties are down.

2. Though his brother-in-laws were dim, they knew enough to yearn to be more A.J.-like.

3. Did you see that beautiful man fight off the pack of wolves to save that baby? What an A.J.!
4. The handsome, virile, and utterly breathtaking man was not only a genius, but almost A.J.

AJ
A slang term for a male couch dweller. AJ's like to have their ego stroked for doing absolutely nothing at all and can be awesome friends, despite their frequent mood swings. AJ's are experts at making girls feel good about themselves and are not afraid to get down on all fours and act like evil kittehs.
