What is this creepy subliminal image in "Black Sheep" (1996)?

The same disturbing image pops up in completely different scenes. It seems to depict a man bound with rope, and sharp implements jutting into his sides and limbs. He may be wearing a mask of some sort, it's hard to tell. The image first shows up when Chris Farley stumbles upon a Rasta band, at about 42:30, and later when he and David Spade are on a bus, at 53:00. Here they are in order: http://ift.tt/2h12iyC http://ift.tt/2hKXYon

Does anyone recognize this thing? What the hell is it?

My internet is too slow for a high-quality stream, so if anyone is able to get a clearer screengrab it would be much appreciated.
