This popular girl humiliates me because I ignore her. What to do?

There's this girl every guy (except me) wants to fuc.k. Funny thing is, she seems to be attracted to me and no one else. She always tries to get my attention. She's a very arrogant girl (thinks she can get every guy) and that's why I ignore her. It's obvious it drives her mad and that's why she feels the need to humiliate me. The other day she asked me to arm wrestle her friend who happens to be a very muscular guy (he reminds me of Jersey Shore Ronnie). "Why don't you arm wrestle Josh? Let's have an arm wrestling match. We want to see who the stronger man is." Then she giggled and pointed at me. I rolled my eyes, told her to stop embarrassing herself and kept talking to my friend. She screamed: "Are you such a puss.y? Are you afraid to arm wrestle Josh?" I told her to shut the fuc.k up and that's when Josh came to me and challenged me. The guy is funny looking. He's very short but overly muscular. I'm tall and athletic, but being tall didn't help me. Obviously. He won.

She said something like: "Wow, BIG SURPRISE... NOT!" Then she giggled and stared at me. She kept smiling and I felt humiliated, but I didn't show her how humiliated I felt. I smiled back and joked about it: "You exactly know I let him win. By the way, why are you unable to deal with the fact I'm not attracted to cheap sluts like you? You're simply not worthy enough to date me. Just deal with it." She got really mad at me and slapped me: "I don't want to date you!" Then she ran out of the room. Her girl friends and Josh kept defending her. They told me I shouldn't have said that. I was being mean to her? They act like she's an angel and I'm the devil. It's pissing me off.

What do you think? Did I overreact? What should I do if she keeps humiliating me?
