At least this acronym took on a life of its own: we now also have CLOBs (which correspond to no English word that I am aware of): https://en.wikipedia.org/wiki/Character_large_object

verb: informal hit (someone) hard. treat or deal with harshly. defeat heavily.

Noun: British slang for Clothes, circa 1879

The Fantastic Four's The Thing's catchphrase, "It's clobberin' time!" was the only "clob" I was aware of prior to doing these searches.
