Bai

1. a more efficient way of saying "farewell" and "fuck you"

2. an extremely effective word used to win any argument (best used when all other insults have been said + especially effective when said to parents)

3. an alternative way of saying "My name is ______. I'm __ years old, and I don't give a f*%k."

5. fruit juice full of antioxidants

Brett: You are a repellent, ball busting, fart taster.
Jake: Yeah, but yo mama is a revolting, heavily built, cock monkey.
Brett: BAI.
(Brett therefore wins the argument.)

Bay

A classic example of a southern belle. Smart, funny, and always incredibly attractive, she's a keeper. While easy on the eyes, they are not afraid to speak their minds, and often do so without any hesitation. Fiery, but also full of intense love, they are caring and full of devotion. Also, they exhibit an uncharacteristic affinity towards popular culture, and can become diehard fans of, for example, Star Wars.

I finally found a Bay that I can bring home!

I hope when I visit Texas, I find a nice Bay to marry.
