The term "swab" is defined as a small piece of absorbent material, often attached to a stick or handle, which is used for cleaning, applying medication, or collecting samples. This could be a cotton ball, sponge, or any other material that absorbs liquids or adheres to small particles.

Overall, "swab out" refers to the act of cleaning or wiping the interior of an object using a swab-like material to remove unwanted substances, whether it be physical debris or metaphorical negativity.
The word "swab" originated from the Old French term "esponger", which means "to sponge or mop up". It was borrowed from the Latin word "spongia" meaning "sponge". The addition of the word "out" is simply used as an intensifier or to indicate the action of thoroughly cleaning or mopping out an object or area. Therefore, the phrase "swab out" likely evolved from the combination of the Old French "esponger" and the English word "out" to convey the act of diligently cleaning or wiping something.
