When you're listening to a really good
song and can't decide what
instrument to pretend to play, so you switch up every few seconds. Most common instruments include: lead guitar, rhythm guitar, drums, and keyboard.
I can't listen to Spraynard cuz I always start
air banding really hard.
"I can't decide between picking
the guitar, strumming the guitar, or drumming, so I'm just gonna air band."
"Dude, who CAN decide?"
