The little man on the boat has a boat boner.

My girlfriend got a boat boner from watching The Notebook.

Get the boat boner mug.
A boner that is so hard that it hurts your penis.
Last night I watched so much fart fetish hentai that I got a bolens boat boner and it hurt so bad that I couldn't even fap without making it hurt even more!

Get the bolens boat boner mug.
When a hoe shoves your dick between her titties and bounces them up and down, pushing them together. Not to be confused with motor scroting.
"Hoe: I know you've motor boated me, but I wanna try boner boating.
Douche: As long as we try motor scroting afterwards."
