Someone who is constantly yelling at you to use star power when you're playing Guitar Hero even though:
1. You just got it.
2. You don't even have 4X multiplier.
3. You're not even at a hard part.
These people will sometimes feel the need to "help you out" but pressing the star power button for you.
Person 1: OMG USE STAR POWER!
Person 2: Dude, ignore the star crazy you should save your Star Power for the solo coming up.
