This video — which was uploaded last year by YouTube prankster DerekDeso — features one of the cruelest pranks we’ve ever seen. Derek and his girlfriend both have popular YouTube channels that feature videos of them playing a variety of pranks on each other, but this prank is next level.
Like a boyfriend with a death wish, Derek decides to spike his girlfriend’s protein shake with MiraLax — a laxative that will do terrible things to your bowels if you take more than the recommend dosage — before she goes to the gym.
But the prank didn’t stop there! Derek sets up a series of elaborate obstacles to make his girlfriend’s inevitable trip to the bathroom a lot harder, and the end result is pretty messy.
