Someone you throw paper airplanes at, perform as a Tourette's child for, compliment on her dress and say you have one just like it (if you are male), and generally confuse and irritate. The ultimate goal is to either make the substitute break down laughing or reveal his/her shocking brain-dead-ness by convincing him/her that you really do talk like that.
"Wow, that sub we had in history was wearing a belt and suspenders."
"I sorry my acc-SCHENT. I haff P H D."

Many desperate YouTubers with fewer than a thousand subscribers on their channel will subscribe to any channel just to gain an extra subscriber in exchange. This is regardless of how terrible the videos are.
