Do guys that are friends "call dibs" on a girl?

Anonymous
I met this guy in one of my college classes...we spoke in class but that was the extent of our relationship. Eventually, however, I was introduced to his friend, and he and I hit it off really well. We went on a great first date and he asked me out for a second one, but then things changed. All of the sudden he stopped talking to me, and his friend (the original guy from my class) STARTED talking to me every day and asking me to do things with him.

I have never given the guy from my class any signals that would indicate I was interested in him, and he was the one that introduced me and his friend in the first place. He was also never interested in hanging out or speaking extensively until after he realized I went out with his friend. I don't understand...if a guy meets a girl first, does that mean he can call dibs on her or something?
