AJ 

It means "american joke", but we can use it as some jokes are not funny, but the speaker who speak it thinks it's funny.

Hey, look at that teacher talking AJ, is he blind so that he couldnot see our faces?

Aj 

Aj may be short but damn he has personality. He is a pretty cool guy. He can rap so well that you will be surprised that he is just a person, not Soulja Boy or Drake or Chris Brown or Chance The Rapper or Roddy Rich or Kayne West or Lil X Nas or Stormzy or Jay Z or Snoop Dogg or Jamie Foxx or Pharrell Williams or Will.i.am or R Kelly or Psy or MC Hammer or Zay Hilfigerrr and Zayion McCal or Silento or Ayo & Teo.
And that is just to name a few. Don't offend him or you will regret yourself someday.

Aj is definitely going to be a rapper one day.

AJ 

AJ is a very complicated guy. He flirts with every single girl he sees and can't stand being single. He doesn't care about people's emotions and only wants what's best for him. He is a fake friend, he won't tell you his true opinion of you until the time comes when you get him so annoyed he will tell you. I would avoid these types of guys as they play with your emotions and only care about themselves.

Oh no, stay away from AJ.
