River Boat Captain 

I fake sexual position used to trick your friends into thinking they are not cool enough to know what you are talking about.

Tom: Did you nail Lisa last night?
Ben: I gave her the old River Boat Captain after she passed out.
Tom: Huh, oh yeah, I've always wanted to try that.

Indiana river boat 

When you mix all your bodily fluids into a bucket with indiana river water and stir it until it thickens up into a lube like texture that has a greyish brown tent to it. Then use it for lube to penetrate your partners holes and create prolapses as it does not actually lubricate your member. Then scrape the remaining contents and the newly added fluids off your member and the prolapse. Place all that back in the mixture place in a cake pan and bake at 425 for 30 minutes. The finished item is an indiana river boat and if you don't eat it all you are not a true hoosier.

My boyfriend performed the indiana river boat on me, the prolapses were almost as good as the meal afterwards

Humboldt River Boat Ride

When you are railing your girl from behind, and as you are about to ejaculate, you pull out and squirt semen in her hair. She is not as thrilled with this as you are.

I took my girl for a Humboldt River Boat Ride last night. She is complaining that she needs to wash her hair.

Floats the boat in your river 

What gets a girl wet and creates a flow of vaginal discharge; enough to float a boat.

You have some weird fetishes but whatever floats the boat in your river
