It’s a dog-eat-dog world, not a doggy-dog world (although a doggy-dog world sounds much more fun).
The phrase “dog-eat-dog world” means a world in which everyone is out to get each other, a much nicer world would be a “doggy-dog world” as some people mistakenly use the phrase.
But a doggy-dog world sound much better, like a world where dogs are just running around everywhere and you can pet them all and they are all so happy to see you!
And when was the last time you saw a dog eat another dog? I vote we change this one.
The people who didn’t win aren’t the “runner-ups” they are the “runners-up.”
This is a fun one! It can be tricky to pluralize words in English especially because we have a few zingers like this where the “s” doesn’t go at the end of a phrase. Other words like this are “cul-de-sac” (plural is culs-de-sac), brother-in-law (plural brothers-in-law), and passerby (plural passersby).
Do you “jive with” someone or “jibe with” them?
This is one that makes more sense the incorrect way. If you “jive with” someone, you get along, you can successfully dance together, at least that’s how I’ve always thought of it. But the phrase is actually “jibe with” which refers to an out-of-date nautical term so if you didn’t know this one, it’s really not your fault.
You do not “nip something in the butt.”
The correct phrase is “nip it in the bud” as in, take care of something before it even gets a chance to start, like the bud of a flower. But nip it in the butt is much funnier so let’s go with that.
