A loner boner is when you get a boner/masturbate to fictional characters because you're lonely and don't have anyone in real life
Guy 1 "Bro, I was playing Persona 5 the other day, and got a boner when i saw Futaba."
Guy 2 "Damn, i thought you said you had a girlfriend."
Guy 1 "I do."
Guy 2 "Then why did you get a loner boner?"
Guy 1 "¯\_(ツ)_/¯"

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.

Bill: ah, that's hot, you got a boner too?
Bob: hell no that's gross!
Everybody: (simultaneously) Loner Boner!
