Top Definition
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!

When a person who has few or no friends and keeps to themselves masturbates.
It seems like all Jeff does anymore is hole up in his room and work out his loner boner.

An erection that occurs when standing on your own. These are entirely random.
The horse standing alone in the middle of the field had a giant loner-boner.

When you think something or someone is hot so you get a boner, but nobody else has a boner or thinks it is hot.
Bill: ah, that's hot, you got a boner too?
Bob: hell no that's gross!
Everybody: (simultaneously) Loner Boner!
