<human>: Can you provide a brief overview of the text?

Sorry if this is the wrong place or if I'm too young or whatever but I'm a 15 year old male. Last Friday my high school had a football game and I basically just hanged out with some friends. Near the end of the game some girl a grade under me asked if I wanted to go to homecoming with (her friend). I've never had a girlfriend or even had a girl show interest in me so I didn't know what to say. I was all red and was like "no, homecoming is gay (fuck me, I'm dumb). She just kinda laughed and said aww then walked away back to her group (including the girl).

My question to you is...what do I do? I've never spoken to the girl before, but I have said to people that I like her. Is this just her feeling sorry for me and is just wanting to go cuz she has no one else or does she actually show some interest? Also, how can I recover from my stupid mistake?
<bot>: Friend of girl I like asks if I want to go to homecoming with her (the girl I like). Not sure what this means and said no for some dumb reason.
