Guys at a BasketBall Game yelling out my name?

[Maria J]

I know I asked this already but, I went to a basketball game and when I was there I was sitting. Then this group of guys that I never had talked to before yelled my name and were looking at me. I just turned to my friends and laughed, because it was weird. By the way this group of guys are the most popular guys at our school and they are seniors and I am a junior. One of them is also friends with my brother who graduated already. What do you think this means? Thank you
