Guy friendgroup acting weird?

I’m aware of things like if a guy has a friend group that either teases him infront of you or they just act weird, it’s a possibility that he likes you and their friends know. Or that they talk about you. However what does it mean if there’s no specific guy, just a guy friend group acting weird? And by that I mean, you find ourselves in situations like intense eye contact with ALL of them, them looking and smiling at you, and more. It’s fine if you don’t know the answer, heck I don’t know it myself. But if you have any idea, please let me know.
