Definition
A long, narrow depression on a celestial body or a fancy term for a groove in the ground—basically nature's way of saying 'I'm keeping this stuff.' Also happens to be a ferocious Madagascan carnivore that looks perpetually unimpressed with your existence.
Example Usage
The lunar fosse stretched for miles, making it the perfect natural bunker for a hypothetical moonbase.
