When you shit and piss your pants because you don't want to stop playing video games

Also known as Gamer's Thumb or Nintendo Thumb, Nintenditis is when some part of your thumb or wrist becomes irritated or swollen due to excessive video game playing. A person with Nintenditis will feel pain or discomfort when bending their thumbs or moving their wrists. Note that this can happen with any finger, and not just the thumb.
