An acronym for "The Be All, End All."
The ultimate; the supreme; the best (see example 1.) Often used in
conjunction with sarcasm, referring to someone not at all the BAEA (see
example 2.)
Example 1 -
Paul: Did you see Tommy pull out that tree stump out with his quad?
Bob: Yeah,
it was awesome, we grabbed a beer after. Tommy's the BAEA.
Example 2 -
Tommy: Shaun fell over this big ass tree stump going out to the yard. He was trying to impress the crew, thinking he's the BAEA.
Bob:
What a clown.
