Flirting

Did I miss hints, my friends say I did?

So last year, this girl who was in my class, who I seldom spoke to, and if I ever did speak to her, it was about school. One day, in a large group chat (it was a group chat with me and the boys), she joined the group chat and began to intentionally try to annoy me, but in a friendly way, she used the same method the boys had previously used months prior to annoy me. I thought, one of my friends probably added her to the group chat and just told her annoy me and how to do so, so I didn't think much of it.

The next day, I walked passed her, and she greeted me and told me to check the group chat. So later I check the group chat, and she had sent that exact message directed at me that always annoyed me, the same as the one she sent the day before, and the same one the boys used months prior, and she sent a heart emoji (there was this one exact message, that annoyed me, it's an inside joke so nobody here would understand, but everyone uses it to annoy me in a friendly way as its just a bit of a pet peeve I have). Once again I didn't think much of it cuz I just though it as one of my friends probably told her about the inside joke, just to watch her annoy me, and see my reactions.

Then she starts trying to annoy me in a friendly way in person, always with a giant smile on her face, once from what must have been at least 50 yards away she yelled at me the message that always annoys me, some of her friends joined the group chat to annoy me. Once her and her friends were all looking at me and giggling, they would look at me, say something to each other and then giggle as they looked at me. I made direct eye contact with them and gestured for why they are staring at me, but they just said something to each other and giggled again.

However, separate from all of this, one of my friends that actually liked this girl, talked to her, and she said she isn't looking for a relationship, I don't know if she just shut him down, or if it was the truth.

Was she hitting on me or not?
