Search Results: catching a girl''s eye

My best friend and me all yr so far have acted pretty cocky around cute girls. We've seen a few guys who acted like players get slapped by 2 of em. We bragged that we knew karate and if any cute chick tried to slap either 1 of us we'd catch her hand easily. Last week though, this 1 really cute blonde chick went up to him. He'd acted that way with her and I was about 10 feet away watching. She raised her eyes up at him and then whooop-out hung her right hand slap, but it was FAST! I was like uhh😵😵! His jaw dropped and she slapped his face sideways, and stared at him and walked off. We both went in the bathroom and he put his hand on his cheek and was like owww😖😖! Her fingerprints were on his cheek. Now when we go back to school I'm worried. She knows we're friends and I bragged too. Her speed, ugh!😖😖😖I don't really know any karate and I don't wanna end up like he did, fr! What should I do?

This girl works in one of the Warehouses I get product from. First few times I saw her she'd only look at me.
Then one time while I was there, I asked if she could let me out of the building. She started saying I was like a dog and I was wanting to go out. That maybe I should beg. I told her I could be like my dog and just hold onto her leg until she lets me out. She giggled and let me out.
A week later, I saw her again, and I kept catching her glancing at me and smirking. I came back later that day and she acknowledged that I came back. I said it was because I missed her so much. She giggled, and said she'd miss her too. Then she was looking at me as she left and then I left.
I haven't been back since, but I'm pretty sure she's flirting just because she's made full eye contact and she always aims her body at me.
Should I ask her out?
