N64itis
When your thumb gets so sore from playing N64 that it feels like it’s gonna fall off and join the Mario Kart racetrack.
After playing The Legend of Zelda for 8 hours, my thumb looked like it was about to start a union strike.
My thumb was so sore I thought it was gonna text my mom for help.
I played GoldenEye so much my thumb had a life of its own.
