 Even before that, going back to the 1840s, we find filthy being used as an intensifier to really kind of exaggerate other adjectives and adverbs to indicate force and impact and indicate just kind of the strength of the word to follow. Not meaning dirty, in no way meaning dirty, but just meaning more of the same. And you find this happening again and again where something, a word is kind of stripped of everything except its force. All that's left is its emphasis. Right.
