rudder slut 

the less-pretty woman you take sailing with you. You keep her in the cockpit to tend the rudder. Her tits aren't nice enuff for her to be a deck bunny.

When the sun went down the rudder slut and I fucked outdoors in the cockpit.

Rudderflutter

When you blow a raspberry at the base of where the penis meets the scrotum. Preferably during erection and foreplay.

Bro, she gave me the best rudderflutter of my life last night. Tickled like a mofo.
