A condition similar to ADHD affecting all drummers who actually love what they do. It causes the drummer to play on any flat surface, vertical or horozontal, which exists within hand reach whenever he or she has at least 1 minute of boredom in band. Often scorned by other band members, conductors, and even other drummers, it is one of the few downsides to being a drummer.
1. Man, Ryan's Drummer's Syndrome is starting to annoy me.
2. Hey, Aaron, your Drummer's Syndrome is messing with our tuning. Mind stopping?
When drummers and wannabe drummers absolutely cannot stop tapping surfaces or playing drumkits in your practice space, despite the fact that the rest of the band needs to sort something out, you've got a case of Drummer's Syndrome on your hands.
"Goddammit, there he goes again with his Drummer's Syndrome! Stop fucking playing, we need to tune!"
