To hit something so hard that fairness stops being relevant.

means To hit, defeat, or criticize someone so decisively that it's no longer a contest.

from Origin genuinely uncertain. 'Clobber' surfaced in British slang around World War II, especially in RAF usage meaning to bomb or beat badly — likely imitative, built to sound like the thud it describes, possibly influenced by 'clump' or 'slobber.' No solid trail runs further back than that, so take any fancier backstory with suspicion.
