The word thizzkillington is a lot like buzzkillington. It is when a person is thizzing and another person keeps bringing them down.
Person 1:"Hey, lets go to the mountian and enjoy this thizz."
Person 2: "Nah, man... I justt wanna go home and sleep."
Person 1:"Man, you're such a thizzkillington."
Person 2: "Nah, man... I justt wanna go home and sleep."
Person 1:"Man, you're such a thizzkillington."
