Guy's Behavior

This guy I like threw me into a pool, what does it mean?

So I went to this pool party and everyone got drunk. My crush walked in and said hi to me and tried talking to me about how he played basketball with my brother but I kind of walked away and forgot I was talking to him. 1 hour later I was having a conversation with my friends and he picked me up from behind and threw me into the pool. (I was in a bikini already) it was night time and his friend yelled "yo that was a random girl, wait just kidding that was ____." After throwing me in he threw in 2 of his guy friends and I was the only girl he threw in. (Keep in mind I was wearing a really unique bathingsuit and I was the only girl there with short hair) Before that I was on a raft in the pool with my friend and he was in the pool when he decided to throw us off the raft. He's known to be an asshole, but he's never been one to me. I barely see him because we go to different schools, but we have a lot of friends in common. I tried to get my friend to set me up with him 1 month ago but he said he couldn't because his little brother is dating my younger sister. What does this mean? Like what is this whole throwing me off a raft and throwing me into the pool stuff?
