Why are guys who are bums the meanest?

I'm being dead serious, in college I attracted a lot of bums. They're entitled, lazy, and most likely peaked some time in high school. AND all they wanted was a hook up. They say the top ten percent of men is terrible well I think the bottom bums are. The cute ones that all have drug problems, the ones you'd die to date as a teenager but are now on a milk carton somewhere. I've had a better adult experience dating dudes who were nerds. They're usually successful, smarter, and more fun to talk too. Sure theirs that top ten percent of guys that are like athletes or something like that but I haven't been out with those guys. BUT WHY, Are the guys who peaked in high school the meanest?
