Sockdolager is a noun that refers to an exceptional person or thing.
Our word of the day seems to have originated from the word sock, a euphemism of punch. To deliver a sockdolager to someone’s mouth, means to punch them in the mouth.
I expected a sockdolager when I told Sally she had gained a few pounds, but instead she thanked me for the fitness advice. But I’ve still said a number of crazy things for which I deserved to be clobbered.
