Half cat

Felicia the Catgirl is a NAKED videogame character.

Refers to a situation where any less than the whole item is worse than having nothing at all. The idea is that while it's obvious that sometimes doing (or having) something half-assed is worse than doing it properly, sometimes doing it half-assed is worse than not doing it at all.

A phrased commonly used to mean any number of things, including "take care," "leave meh alone," "we are talking in code now," and simply, "do not cut your cat into two equal sections."
