When a destiny player has nothing else to do in the game therefore they begin to slide around the social space, the Tower. Often mistaken for playing the game.
I've just handed in all my bounties for the day, now I'm bored I shall tower slide around to waste time and pretend I'm playing the game.
When you roll a slip n slide off the Eiffel Tower, or another tall slanted structure, and go slide down, to your ultimate demise.
“Hey, wanna come with me on the Eiffel Tower slip n slide”
