nintendonitis

A chronic painful condition that effects the muscles or joints in the hand, fingers and/or forearm after playing videogames too much.

Dude, I played Final Fantasy for three days straight, but my Nintendonitis flared up so I couldn't play anymore.

Nintendon

A hand or finger tendon that gives a player the quickness and flexibility to master video games, especially games that require great dexterity and precise button pressing sequences.

Tony's Nintendons give him the fast fingers to crush Sang in Street Fighter.

Nintendonitis

The cramp you get in your hand from playing video games, especially between the thumb and forefinger.

I was winning blades of steel until my old Nintendonitis injury took me out.
