Not too sure if you have noticed this but I added this hashtag recently on my Bio.
I did that not simply because I want to be "atas" and not be related to anyone besides that fact that you are really not, but I have my reasons.
Let's break it down and look from the other point of view. So why do you even call someone bro?
1. When you don't remember a person's name
2. When you need a favour
3. When you want to force a false sense of bond for certain reason
4. When you guys are really close
5. When you guys are really brothers (maybe not even actually)
So unless you are point 4 and 5, which is actually very seldom,(if you put some thoughts into it, your closer friends don't call you bro.) there is no good reason to call anyone "bro".
And more often, someone call you "bro" because of point 3. Creating this false impression of closeness and to make you like him or her and feel obligated to help.
"Hey Bro, do you mind if you pass me this?"
"Bro, my car ran out of coupon, got one to spare?"
"Bro, this one my friend, can help and give a chop and let her enter 1st?"
"Bro, got lighter?"
"Bro, help ah, give chance ah. I park awhile only, go pee ah. 1 chance ah bro."
Do not fall into this mind trick. So yes, do not call me bro. It pushes me away more than pull me closer because I know it's a lie.
I mean, unless my dad really did have sex with your mum or the other way, else, we really ain't bros.
Mr.Smith, we ain't no bros.
