An event occurring on Sunday evenings when the alpha-male suddenly realizes that his nightly escapades suddenly seem for nothing as he is completely alone, finding himself laughed in the face by his suddenly erect boner and no one there to disarm it. Hence loner with a boner.
Oh, Jeffrey... he may be a stud on occasion, but come the day after he is only a loner with a boner.

A boner or erection that occurs in one's home, or in any other place alone. This includes when they are looking at porn or reading/thinking about something erotic. A Loner Boner can also occur when somebody unattractive is around, such as a parent. However, if you are with a girl (or boy, depending on your gender preference) and you get a boner, this is not considered a Loner Boner.
Jeff: Dude, I just got a total Loner Boner last night.
Mike: What did you do?
Jeff: What every civilized man would do! Took advantage of it!

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 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)_/¯"
