In the 1970s, bro came to refer to a male friend rather than just another man. The word became associated with young men who spend time partying with others like themselves. Oxford Dictionaries identified the use of the term "bro" as the one "defining feature" of the changing cultural attributes of young manhood.
Some men call everyone bro, and that includes their female friends. It's a habit and doesn't mean anything.
They are expecting the same kind of respect from your side and calling them “bro” makes them feel that you are disrespecting them by doubting their attentions regarding to you.
Why do most men call each other “man”, “dude” and “bro”? Well most men don't first of all…these terms of endearment are used mostly by younger, western men as a means of showing respect, love or as general informal way of addressing everyone considered as equals or lower on the social scale.
"bro" is a shortened form of "brother", so calling someone your "bro" is like calling someone your close friend. I wouldn't say it to someone I just met. You can use it whenever you feel like it, if you don't feel comfortable saying it, you don't have to.
“Bro” is short for brother, which could mean she sees you that way. Thinking of you like a brother is even deeper than friendship—it means she truly feels like she can be herself around you. Again, this isn't a bad thing at all, but it might not be what you're looking for if you like her romantically.
Men like being complimented on their appearance, as well as their personality. Nicknames are a great way to express affection and familiarity. "Cutie" or Good-looking" are great nicknames when flirting, while names like "Babe" or "Honey" are better for committed relationships.
A girl calling you “dude” doesn't necessarily mean you're in the friend zone, but it could be a sign she doesn't want anything romantic. Pay close attention to if she calls other people “dude” or if it's just you. If it's just you she says it to, then she may be trying to politely point out she's not interested.
Is Dude A Friend Zone Word? Dude is not necessarily a friend zone word, but it can be. If a guy has no romantic feelings for a woman whatsoever, he might call her dude to let her know that he views their relationship as strictly platonic and nothing else.
If a boy refers to a girl as his "bro" and they are not friends, it could be interpreted as him having friendzoned her. However, if they are friends or have a close relationship, using "bro" in that context may just be an informal way of addressing her.
He thinks you're not interested in him
One of the reasons why guys don't call when they like you is when they don't know whether you're interested in them or not. Sometimes they need a little more nudging to make the first move. They tend to call more freely when they're sure that you might reciprocate their interest.
For those who have no clue about what I am talking, Urban Dictionary describes a bro-chick as, "Chick who is basically like one of the dudes, similar to tomboy status, but less manly. One who hangs out and does dude-ly things, but knows her limits."
“Dude” is just a word after all, and it doesn't mean anything more or less. It's not a definite sign of liking someone nor is it a clear indication of dislike; it's essentially a sign a guy is comfortable and sees you as someone he can be friendly and maybe even playful with.
What is the female equivalent of “bro”? 'Sis' is the obvious answer.
Things You Should Know
Shy, playful, and frequent touches are signs of a crush, so if they don't do this, it means you're in the friend zone. Think about what you do together. If they often invite other people out with you, try to set you up, or ask you for favors, you might be in the friend zone.
Guys that are into you often use lots of emojis, text first, or even double text. Watch for in-person signs, like holding eye contact, respectful little touches, or leaning in close. A follow-up text after a date or hangout, or a raincheck when he can't make it are sure signs that he wants to spend more time with you.
A guy who likes you will always be nice and polite in his approach towards you and he will always look for avenues to spend more time alone with you and get to know more about you- either by going on a date, through constant phone calls or chats- the subtle signs are always there if you pay close attention.
Men prefer a woman who can stay calm and relaxed. Beauty is more than make-up and a fancy haircut. Men find women more attractive when they are neat and clean. Men find women who smell nice, who have clean hair and hydrated skin more attractive than a face perfectly covered in makeup.
Men love women who are thoughtful, caring, loving, and kind. A woman who does little things for her man for no other reason other than that she loves him. A woman who makes him smile back whenever she smiles at him. A woman who radiates love and warmth from her heart.
