Guys, Do guys live by the "Bro Code"?

For example, if two guys (who are friends) like the same girl, how will they go about that? Will one guy surrender her to the other who likes her more? Will they both go for her and she gets to choose whomever she likes better? Will neither go for her so they do not cause conflict in their friendship? I'm just really curious.
