Jackopedia
Jackopedia is when your hand is stuck doing the same thing over and over, and your cock is never down. It’s super common and can kill you if you don’t get a break.
My friend got Jackopedia after his mom left him alone for three days.
He did it in the middle of a test and got a zero for not paying attention.
He tried to stop, but his hand wouldn’t listen and kept going.
