A Quinnvention is an invention or experiment that Quinn Pensky makes. The word, created by Quinn, is a portmanteau of her name, Quinn, and the word invention. Quinnventions seemed to be more frequent during Season 1 and Season 3. In Quarantine, she creates a gas that keeps everyone in the dorm on lockdown. She tests on Dustin frequently, and pays him to do so. For example, she shocked him every time he tried to fall asleep. Another object Quinn has invented is the zap watch; she made one for her ankle as well. In Robot Wars, Logan makes fun of Quinn by saying "I am Quinn from Dorkon!" She had to go get a sprocket.
Quinnventions are introduced in New Roomies. Quinn explains to Zoey that her name is Quinn, and she invents things. So she calls her inventions "Quinnventions" as a portmanteau of her name and the word "inventions". Zoey akwardly refers to this as "Quinntresting".
