"It Is What It Is"

A simply lazy way of explaining "nothing".

Nothing and I mean NOTHING simply "Is what it is"!

That would mean (someTHING?) is nothing and there is no such thing as
nothing! It is a word without meaning.

I looked this up because I am sick of hearing this phrase spoken by
people from every walk of life.

Nothing is Nothing and therefore by it's own definition does not exist.
