serfboard 

When you want to cross a river but don't have a board, so you tie your peasants together and ride them across. Invented by Leonardo da Vinci in 1634.

Sarah: I left my boat at home yesterday, so my jamboys drifted me across the river.
Jake: ah yes, the serfboard. Quite a fear of engineering.

When a peasant starts an uprising so you have to waterboard them.

Jake: my slaves got out of control today, so I had to waterboard them. I hate my serfs
Sarah: ah yes, the serfboard. I remember the first time my father let me serfboard our servants.

southern surfboard 

A very risky maneuver when you go out on the swamp and find yourself a gator. Once you get on that gator, you risk your tootsies by dangling them over the mouth hole of that gator.

Me and my cousin snuck out to go southern surfboarding this weekend down in the glades.

mexican surfboard

A guy lays down and a girl sits on his dick. She puts her legs on both sides of the guy and starts bouncing up and down, riding him like a surfboard.

Guy 1: How did things go with you and Rachel last night?

Guy 2: Great, she gave me a mexican surfboard.

Hanging ten on a southern surfboard 

Going to the swamp, and "surfing" on a gator with your toes hanging near the gator's mouth.

Bob: Hey, buddy! How was your weekend?
Buddy: Oh, you know. Just hanging ten on a southern surfboard.
Bob: Damn. How many toes did you lose?
Buddy: surprisingly, only 2. Garry Gator is getting used to me.
