Yeet

An expression used when entering a room where the presence of mice or other rodents is known, especially in old houses. This is intended to inform the rodents that someone is about to enter the room, and they should hide or run until said individual has exited the room.

Yeet!
(The mice, hearing his obvious planned encroachment, hide until he leaves)
