What does it mean when a guy calls another guy "bro"?
Do they mean that they think of you as their brother?
If a guy calls you bro, it's more of a slang versus saying hey Joe. You'll also hear guys saying cuz and are not even related. I guess bro could also be used if they consider you a brother even though you're not.
Its like calling someone dude
Simply means "buddy" friend, i mean i call my dude friends bro all the times but usually are the closest ones to me.
Brother it means your very good bffs like bros or brothers
Just another name for buddy.
