"Out!"

SHOO

Think of the sound you might make to quickly chase away a pesky cat or bird from your porch.

"Out!" is a command to leave, and "SHOO" is the casual, often playful way to say it—like when you wave someone away or chase off a pesky animal. The clue plays on the direct meaning of the word, skipping any hidden wordplay or tricks. It’s a straightforward definition where the answer mimics the sound and action of telling something to get lost. Think of a parent shooing a cat off the counter or a friend jokingly telling you to scram.
