airholes
Gaps for oxygen
Airholes are openings that allow air to pass through or into an enclosed space.
A box for transporting animals needs airholes so they can breathe.
Ice on a lake may have dangerous airholes where the surface hasn't frozen completely.
In casual speech, someone who's an airhole is stupid or worthless—a euphemistic blend of airhead and asshole.
