A ruckus is a noisy disturbance. Cause a ruckus, kick up a ruckus, quite a ruckus.
It is American, informal and slightly comic, so it suits an argument in a car park rather than a riot. Kick up a ruckus is the standard phrase. Britain says rumpus or fuss, and rumpus is probably one of the words it was built from.
