track pad cramp

when your wrist is cocked up at an odd angle to use the track pad on your laptop, and after a prolonged period of time, it results in a painful cramp in your forearm.

sutton: I was on tumblr for two hours last night while i was sitting on my couch, and I got a nasty track pad cramp!
emma: aw man that's the worst....
sutton: yeah i know.... even when I stretched and massaged it, it took a long time for it to go away!
