First, "unlock" the game Get On Top by hitting
UP, RIGHT, DOWN, LEFT, UP, RIGHT, DOWN, LEFT, X
at the main menu.
It's a real weird tug of war game I like a lot. Anyway, have two controllers turned on. Prop the first controller in a way that the Right Stick is stuck facing right. (I wedged a coaster in there.) Set it, and forget it! The trophy will ding after a while. (It took me most of Sharknado 2 to unlock it, so it's not quick.)
