Mississippi Mud Boat Ride

5 or more men performing anal sex in-line with each other. Extra points if it's incestuous.

Hey Tom, the guys wanna know if you're in for a Mississippi Mud Boat Ride this weekend?

Mississippi Boatride

When two people are having sex in the shower and one of the two people drop a deuce. The deuce then slides to the drain like a boat and swirls around in the drain.

Female: "I can't believe that you did that in the shower this morning!"
Male: "They refer to me as the captain of the Mississippi Boatride."
