look up any word, like the eiffel tower:
 
1.
A song that's so catchy, you just can't help but perform it. Over. And over. And over again. A musical itch that you just can't quite scratch.

Like an earwig... but for performers.
I've had this fingerwig for a week straight, now. I've had to bandage all my fingers, I've been playing it on the guitar so much.
