Mad Bass Twitch
The Mad Bass Twitch is when bass hits you and your legs start shaking like you just got electrocuted by a sock full of batteries.
I was in the middle of a math test and my legs started doing the can-can.
I was trying to eat my lunch and my whole body started shaking like a soda bottle on a rollercoaster.
I was just standing there and my legs suddenly went into a full-blown dance battle.
