A trite, overused and infuriatingly meaningless cliche that is utilized by provincials who think they are adding some deep, meaningful insight during a discussion when all they are offering is senseless, unwarranted repetitiveness to what would otherwise be a far better conversation had they not shown the shallowness of the gene pool they spawned from by using this asininely useless and redundant phrase to begin with.
An interesting conversation is being had, when quite suddenly:
Robin: My house burned down last night. It is what it is.
Aidan: Fuck you, provincial.
