The trippy change in vision where everything seems to be constantly moving up after playing guitar hero for extended periods of time
Man, I played guitar hero for 5 hours yesterday and then the guitar hero effect set in as soon as I turned my tv off. It felt like I was trippin balls.

The phenomena which occurs after desperately trying to either pass or 5 star a song in Guitar Hero / Rock Band / or any other music game.

After trying for what seems like ages, then giving up for an extended period of time (usually when a new Halo/CoD comes out or something). You return to the song and easily complete your objective.
I could not for the life of me, 5 star Free Bird. I gave up and played Halo 3 for a few weeks. I came back Guitar Hero Effect came into play and I easily achieved my 5 star.
