awkward & embarrassing moments | High School | Drama

So this guy asked me to go out for lunch with him and I did. We don't know each other that well. A friend kind of set us up. Anyways he's really nice and i thought he liked me. One time in class he came up to talk to me then his friend just shouted "stick it in!" At us and it was super awkward and probably embarrassing for him. At the time we were still getting to know each other and so after the comment I walked away. This happened about 2 weeks ago. He hasn't talked to me in class or sent me a snapchat. So does this mean he doesn't like me? He doesn't really acknowledge me either. One day I said hi but he didn't really do anything. Last week he was hanging around one of my friends who was standing near with me and we were talking when this guy would add in on the convo but more directed to my friend. Anyways today I sent him a snapchat just saying hi.
