minnesota shower 

To cum on one's own titties.

Last night I was working something out on my own and accidentally gave myself a Minnesota shower

Minnesota Shower Rod 

When a male truck driver takes a Viagra and experiences an erection that lasts longer than 4 hours, he then has sex repeatedly in a 4x6 hotel shower trying to relieve his massive boner.

After my long drive to Minneapolis, I had me one hell of a Minnesota Shower Rod when I saw my mistress.
