A stunning, weird and freaking awesome friend that you will ever have. She may not be responsible but she's loyal and can keep the deepest secrets. She may not be smart but she is kind of wise. And maybe those are the reasons I fell in love with her.
Bai is awesome!
Look what Bai made!

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.)

Another way of saying "good-bye," or "bye."
Why it is spelled in such a way is beyond me, but it is catchy. The word bai is used in the famous internet phrase "kthxbai."
I have to go now, but ill see you later. Bai.
