When you're so wasted that you fail to pronounce "Bro" so you just say "Boo"

"Boo can you pass the blunt?"
"Stop drinking for now, you're already wasted af Boo"

Use 1: Spookiest most spoopy thing ever.
Use 2: What you call your significant other. I find it cringe.
Use 3: What the crowd said to you about your talent at the school talent show.

Person 1: Boo!
Person 2: Dude, don’t scare me like that
