Everybody’s going bro this and bruh that, but you’re not my brother, dude 😒
It’s not like either word is new but I feel like “bro” and variations like bruh or brah have become way more commonly used in the last decade among younger people as a term of address in contexts where I would have just said dude


Oh yeah, definitely.
I’m from the UK. We’ve said it for as long as I can remember, but mate is way more common.
Edit; amongst numerous others.
I have fond memories of my elementary school teacher in the 80’s (northeast US) getting absolutely enraged anytime someone in our class said Dude. And she would respond with “
A DUDE IS THE FIRST HAIR ON AN ELEPHANT’S ASS!” and we loved it. 
This has just reminded me…I called a manger “dude” in a Christmas Day text, years ago. He went on a massive rant about it the following year.
Lol about the elephant hair thing? Or just about dude?
Me calling him dude. It was something like “happy Christmas dude, hope you have a great day”, so he bore that grudge until at least the 2nd of January, and went on a rant at me.
Lol total dude move.
