Idioms. Clichés. Metaphors. We all use them without thinking about them. But did you ever wonder where sayings such as "sick as a dog" come from? Language is an amazing thing. It's constantly evolving with slang, social progress, and technologies. While new words like "selfie" and "manspreading" are being added to our lexicons and dictionaries, some old school ones have remained with us for decades and even centuries. Some of these phrases might have made sense back in the day, but not anymore. Yet they have lasted the test of time in American English.
