Definition
"Rat-a-tat" is a sound that resembles a series of quick, light taps or knocks, often repetitive. It's a rhythmic sound, like someone drumming their fingers or a woodpecker pecking. Think of it as the sound of someone impatiently knocking on a door. It's usually a light, rapid percussion. Unlike a single knock, rat-a-tat suggests a sequence. It can also convey urgency or impatience.
