'Nip it in the butt' or 'Nip it in the bud'?

Transcript

Sometimes a word that sounds like the right word and feels like the right word isn't actually the right word. It's an eggcorn. You don't nip something in the butt if you want to stop it before it gets worse, though, maybe that would work in some cases. No, you nip it in the bud. You figuratively pinch off the bud before it opens into a leaf or flower.
