Gemme that neck

When someone does something stupid you get their neck by slapping the back or any part of their neck with your hand and as soon as some one says "gemme that neck" you say self serve. And if that person says no neck no nothin you could say the word "Peace" to save your self

Matt: I thought it was tuesday
Eric: no. Gemme that neck!
Matt: self serve
Eric: neck no nothin
Matt: Peace
