To perform a pootash you must, firstly find a victim, secondly rub your finger around your butt hole until it stinks of shit ( how much rubbing depends on your personal hygiene), thirdly rub said shitty finger across the top lip of said victim. If performed correctly the victim smells shit all day especially if pootashed without their knowledge.
I pootashed Jim while he was sleeping and he’s been trying tofigure out why he can smell shit when nobody else can.
