Would you give up a girl for your friend?

If it's ya best mate he wouldn't even go after her no matter how much he likes her, unless he said he liked her before you where going out with her and then that makes you an asshole.

I would do it because most of my male friends are ridiculously virgin losers. I mean the kind of guys that most women would look at with disgust. If I could afford it, I would pay their way to an all expenses paid trip to the brothels in Nevada. Remember kids: friends don't let friends live and die as virgins.

Yes, absolutely. I would give up a woman for one of my friends.

It wouldn't seem right for her to be off limits to both. Maybe it's best for her to know that both have an interest and let her show a preference. Both guys aren't likely that much the same and one is more smitten than the other.
I was recently in a club where I met a good looking girl with a great sense of humor. She really had me paying attention. I had seen her before but she had a friend then. Now she was there alone. But later her new friend showed up and it turns out I know him. So she's off limits in my book. In fact, I'm likely not to hang out around him much in order to avoid situations where I might be tempted to flirt. But if we had met her at the same time, it might be different.

If I knew it wasn't going to work and planned on breaking up soon, then yes. Otherwise, no. General rule is "First come, First Serve." There is no reason I sacrifice my relationship. If she is truly interested in him, she will leave me for him. It's like in Spider Man where Harry Osbourne snatches MJ before Peter did but Peter still ended up with the girl at the end. You can't really gift a girl. Don't think she would like being stuffed in a box either.

If the guy is really your best friend, and you are currently already going out with the chick, the best friend would let you. You wouldn't dump her so your best friend could have a chance, that's like sharing a girl. The best friend would want you to stay together with the person because they know you got to her first.

People shouldn't give up girlfriends just to please friends, unless there's some serious issue involved.

In my opinion

Speaking on behalf of a girl I don't think that the guy that is actually with the girl should really do anything about it. Yes granted, both of the friends like this girl, but one just moved quicker. If he were to break up with her then there is a possibility of all three of the people involved being hurt. The guy, the girl who obviously likes her boyfriend and the best friend. Chances are that she's not going to go date the other guy after a break up with his "best friend." No girl would do that, and if she would do that, then you shouldn't be with her in the first place. And plus if he really is your best friend, he should understand and respect both you and your girlfriend and want both of you to be happy.
