Top Definition
UAB
Under Age Booty. This term arrives from one of Maryland's elite overseers of the young. Coined in 2007, the use of this term has been passed around in a tight circle (no pun intended) of friends and acquaintances. Whenever one sees a UAB, one must at least acknowledge the presence of said child. The official saying of UAB fans is: The younger, the better.

The best place to find the U-est UABs is the hospitals when they are born. However, access is not always available so it is suggested to go to child's places such as Chuck E Cheese or Pump It Up. Although public demonstrations of UAB love is frowned upon, a UAB-ist should show it proudly and high-five, hug, kiss, then have intercourse with the finest and U-est UAB they can find.

This definition has indeed been written by the originator: ShiningSeoul.
Bob: Hey you see that UAB over there?
Todd: Yeah?
Bob: So tight.
Todd: YO WHAT THE F---

Johnny: Do you know who's cute?
Ralph: Your brother.
Johnny: ...why?
Ralph: Cause he UAB.
Johnny: Dawg, you is gay.

UAB
Unmanned Aerial Boyfriend. A male who constantly follows his girlfriend from a distance to keep track of and deal with any other males she might encounter. Similar in mannerisms to "helicopter parents", except more difficult to spot and not as prone to action. their girlfriend might not know they are there
"Dude, I got paired with this hot chick for the group project!"
"Awesome! did you make a pass?"
"Didn't get a chance. She had a UAB two tables over. I couldn't even spot him until he came over and kissed her!
