Been asked out or have asked someone out? How did it go?

I had this one rlly fucking mean guy ask me out. He bullied a lot of students smaller than him and timid, he smoked behind the school, in his car, wherever. The most basic high school bully/druggy. Before I got in my car at the end of the day, he stopped me and said he was into me and stuff. I thought 'the fuck, u look and act like an autistic rat, hells no'. What I actually said was something like, 'uuuhhhh sorry but no'. I then got into my car locked it and fucking blasted out of the parking lot. This experience hurt me mentally and physically.
