What is the weird behavior or flex you see men do that they think attracts women but doesn't?

I'm asking because I used to have a guy in my neighborhood that had a little crush on me and when I was around he'd start acting aggressive out of no where. Not towards me, but just in general. Like one time I walked out to get my mail and he was in his yard with his dog. Before going outside he seemed to be acting normal, but after he'd see me he started yelling comands at his dog like he was trying to train it or something, but it was REALLY aggressive. He'd also yell the N word a lot. As soon as I went back inside he'd stop. This happened a lot and it was really weird and off-putting. He tried inviting himself over to my place a couple times. No sir, I'm not turned on by your violent outbursts and I don't want you in my home.
