When you are playing rock, paper, scissors and all you give is rock. Also used when an action is seems like it would be repeated. Often you the action changes on your turn. Usually used in reflection about a game.
Bro 1: "Dude, Why did you put paper?"
Bro 2: " I don't know. I thought he was rock-sliding me."
"I thought thirteen would win, it has been played 4 times in a row, but I guess the roulette was rock-sliding me.

When two buddies collaborate, and one buddy shits on his good buddy’s chest, starting toward the top and it slides down the body. This isn’t a “taking the top off” type of shit, this one typically occurs after a sloppy burrito, lasagna, chili, buff chicken dip, etc. just a real beastly shit so it has the proper balance of “firm foundation” with some “liquidy mud” to ensure proper slip n’ slide physics.
One night at the Lighthouse, Jeb gave Nate the ole’ Trans-American Slip n’ Slide. Nate absolutely loved it! He begged for more, and never wanted to leave the lighthouse. Some say he’s still there, at the lighthouse, waiting for another Trans-American Slip n’ Slide.

When one man (or woman) gets on their hands and knees and inserts a funnel into their butthole as another pours milk down the tube into their ass. After this point the milk chugger will have to shit and diarrhea will fly out of the funnel backwards creating a reverse slip-n-slide.
