“Hey bro, what’s up?”
“How you doing man?”
“Duuuuuude. That’s crazy.” Alternatively,
“[instead of person’s actual name just say dude here] [literally whatever else you want to say]”
That’s kinda how I use them. Generally just a replacement for the person’s name
I don’t think I’ve ever used homie before, or even heard it for that matter.
Edit: How could I forget? BRUH. It can’t be used enough. Except not really as a name. Well, kinda. Say it whenever your exasperated, shocked, or sympathetic. That doesn’t make sense. But I try.
“Bruh, you serious?”
“That’s a bruh moment.”
“Sorry bruh.”
