The theory that when bitches are offered granola, they are unable to resist their inner biological urge for granola; therefore, bitches love granola.
1. "Yo, guess what my girlfriend ate for breakfast this morning."
"Granola."
"Yeah, how'd you know?"
"Duh, BLG!"

2. Guy: Hey bitch, want some granola?
Girl: Yeah!
Guy: Damn right. BLG!

BLG
The band alson known as Boys Like Girls. They were a good band until they somehow got on TRL and now think they are the most famous shits alive. The band is lead by flake ass lead singer Martin Johnson, who is not single anymore, so sorry dudes and dudettes, but mostly dudes. Now that they are ruined and complete lame asses they will probably turn out like Fall Out Boy and be just as dumb as Pete Wentz and his suicide attempting ass.
"BLG can throw themselves away and make their Great Escape into nothing and die."
