A person who is strange and consistently says dumb things in social settings. Almost always dorky white guys, incels, who can't get laid. Being a loner is a character trait possessed by all mass shooters. Granted, not all loners are mass shooters; but all mass shooters are loners.
Last night, I saw that loner next door out in his garage working on something with a lot of wires coming from it. Better call the FBI.
