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.

Mike: What did you do?
Jeff: What every civilized man would do! Took advantage of it!
