The proper recipe for “The Smell” is to
take one box of Instant Garlic
Mashed Potato mix and place the cooked contents into an air-tight plastic container. Place said container on top of a warm electrical surface like the top of a refrigerator. Wait 16 weeks. Next identify someone you dislike and leave the opened plastic container in their place of residence (Preferably by an air exchange vent). The unique aroma of The Smell will induce immediate and violent spells of vomitting.
Sit back and enjoy.
