5.
Bay Area Rapid Transit
Trains under and above ground in the SF bay area. They even go UNDER THE BAY.
Sort of ridic expensive.

A lot of people depend on them so when they strike or break down, everyone's fucked.
Lindsey: Let's all go to Berkeley tonight!!
Michelle: We can't all fit in your car though, and mine's in the shop!
Monique: I know, we'll take BART!

7.
A guy who is caring and sporty. He can make you laugh, is extremely kind and probably gorgeous. He is a lot of fun to hang out with and is very original, creative and can entertain you endlessly.
If you ever get hold of a Bart: never let him go, you'll regret it.
"Damn, I turned that guy down, he asked me to prom with him."
-"What?! But he's definitely a Bart!"
