brother 

Someone you love and respect. A brother doesn't have to be a blood-related sibling.
Coming from a guys perspective in the Midwest, it is not often when a friend, relative or acquaintance calls me "brother", "bro" "brotha" or "broseph". Calling someone any of the those words is exactly like saying "I have positive feelings for you, and I love you, man." In a heterosexual, your-my friend-and-I-respect-you way.
For example, over the past year, the only time I called an acquaintance "brother, "bro" or "brotha" was when when I liked them, and thought of them as somebody pretty much love (for who they are)

Seth: "Happy birthday, brother."
Jared: "Thanks"
Seth referred to Jared as "brother" because he loves him like a brother, even though they are not related.

This could be possibly one of the worst things a girl can say to a boy. At this point in your relationship with a girl, there is virtually no hope of you getting with her as a potential lover. You have just unknowingly taken the path of brotherhood and left behind the path of lovers. To all boys, be weary of your relationship with a girl before you end up in "brother territory".

jack: hey bro, I've been talking to Jill for a while now and tomorrow's her birthday. I think I have a shot at being her boyfriend!
mack: Watch out man.... I don't want you to end up as her brother
jack: WHAT? Oh shit... Whatever, she knows what's up

---------------next day-----------------------------------------
(Jack and Jill are alone together)

jack: Hey jill! I got you something. (pulls out present)
jill: AWWWWW, JACK! I LOVE YOU!
jack: *smiles* Jill, will you go ou....
jill: LIKE A BROTHER!
jack: ....
jill: you were saying something?
jack: nope....

brother 

1. a male sibling.

2. a make friend that treats and loves you like a sibling.

I have 2 brothers, one is 9 and the other is 16.

My friend is more like a brother; he's always there for me and listens to me whenever I need him.

Brother 

a smartarse boy that you have to love by law of blood but otherwise find infuriating, often funny but not as much as they like to think. The enemy of the 'sister' but can be a great laugh. As annoying as it is a brother is loved by all especially the ladies (mostly the sister's friends) not to be trusted with all secrets as you may be at risk of mocking but will always stand by you when it really counts. Try to love them despite the imperfections only you know about because nothing is forever and one day they might not be there anymore.

Her brother was in a car accident ..
