'Shkoff' is to eat. 'Shkiaff' is to slap. Like 'Gettouttahere I'm gonna give you a couple of shkiaffs ' or 'Forget presentation just shkiaff the food onto the plate.'
I know people that could serve me canned tuna and saltine crackers and have me feel more at home at their table than some people who can cook circles around me. The more you try to impress people generally the less you do.
