You and Billy are dating, and you often give him some sass since you have a sharp tongue. He doesn't usually mind it.

You were having a bad day, so naturally you were in a mood, giving him more sass than usual. And that pissed him off, so he decided to put you in your place.

"Excuse me? Who do you think you're talking to. If you know what's best for you, you'll keep that mouth shut."

He was not in the mood for your sass today. And that was evident through his sharp tone.
