I wanted to teach you a handy comeback that is usually used in the Caribbean Latino community, from my experience. Anytime someone says something fucked up to you, you say something back and then add “¿en qué quedamos?” Here is an example:
Her: Tu eres una fucking bitch!
You: …and you are a puta so ¿en qué quedamos?
¿en qué quedamos? means “where does that leave us.” Think of it as the American, “and what?”
That’s all, carry on.
