A.B. 

The closest friend that can be desired! A girl who is Funny, Beautiful, fit and considerate. Although being all over amazing will not allow herself to believe it and always stays modest. She is also a bit strange but in the best way possible!

"Hey, that girl is SUCH an A.B.!"
"I know right, she really is"

A&B 

Agonizing Butt-Hurt. A term used to describe people on social media who post vague comments to make other people wonder about their well-being to get attention; and/or make a great big deal about every insignificant event in their life to make people feel sorry for them; and/or make inappropriate comments to other people about life being unfair out of ignorance because they believe that life is "harder" for them. Can be used as A&B or A-B.

John: I saw that Ashley said that she had to make the most important decision of her life today, is she okay?
Adam: Yeah, she's just painting her room a different color, she's pulling an A&B (agonizing butt-hurt).

Lindsay: I got six teeth removed on Monday, it hurts like hell.
Jack: Yeah, when I got one tooth removed, I thought I was going to die.
Lindsay: Are you serious? Don't be an A&B (agonizing butt-hurt).

Don: My kid has to go to the hospital for regular physical therapy sessions every week after being in the hospital for 2 weeks, it's exhausting.
Alex: Yeah, tell me about it, I had to take my kid to the ER twice last year, AND I had to take him to the doctor to get shots. Ugh, parenting sucks.
Alex is pulling an agonizing butt-hurt move.

A.B. 

The A.B., (also known as the Aryan Brotherhood or The Brand) is a prison gang numbering about 15,000 members in and out of prison. In March 2006, four leaders of the Aryan Brotherhood were indicted for numerous crimes, including murder, conspiracy, drug trafficking, and racketeering. According to the FBI, although the gang makes up less than 1% of the gang population, it is responsible for up to 26% of murders in the federal prison system.

The A.B. killed another inmate today.
