the hash slinging slasher means: This is the most frightening monster you can imagine. When he was head fry chef at The Krusty Krab, his hand got cut with a knife, it was a tragic accident. He still uses a spatula to cut his fingers. Here are some signs that he’s coming. You will see the lights flickering on and off. There will not be anyone there when the phone rings. Good luck if you see the Hash-slinging Slasher. (in Community Dictionary, added by Cándida Ramos)
