The Butt Of Your Own Joke

(My husband and I are discussing a poor behaviour our puppy is exhibiting.)

Husband: “I mean, if we don’t nip it in the butt—”

Me: “HA! Did you just say, ‘Nip it in the butt’?! It’s ‘bud.’ ‘Nip it in the bud.’”

Husband: “What?” *laughing* “No, let me finish.”

Me: *laughing* “Oh, my gosh. ‘Nip it in the butt.’”

Husband: “What does ‘nip it in the bud’ even mean?”

Me: “I think it has something to do with flowers.”

Husband: *not convinced* “I think it’s ‘nip it in the butt.’”
