When she's "not in the mood".
Man, we were fuckin' all alone at my house.. Lights out.. Under a blanket.. And then I find out I've got a loner boner.

A boner that appears without warrant and often by itself with no other boners around. I.E, a boner appearing at a strange time that no other man would find sexy.
A spontaneous boner, if you will.

The phase where one enjoys being alone and not in a relationship. After being single for many years enjoying the lone times and fearing the loss of that if they get into a commitment.

a person who usually shows up to places/parties by themself, alone, and with no friends at that time.
I usually go to hip hop shows by myself, but I hate going to places by myself, I feel like a loner boner :(

When someone is so lonely and haven't gone out of the house for days when they begin to find the silence sexy they might get a loner boner.
Guy: I haven't been out for ages! I'm so horny, and its so quiet in here...oh god no I feel a loner boner coming on.

lonely
being by yourself
with no friends what so ever
pretty much having nobody next to you, to make fun of people with.
