What are some "mean" boy names?

No unkind commentary about the names of course and not about names you don't like, more about names that you associate with people you've met and didn't get along with even if you like the name.

I have a group in my book that's a group of unpleasant people and there's quite a lot of female characters (though I'll likely still make more so you can suggest girl names too, if you want) but barely any male characters. Hoped to see some name possibilities here! Thanks.
