What is it called when someone says the opposite of what you say?

There are several ways to describe someone saying the opposite of what you say, depending on the context and intent:

If it's playful or sarcastic:

* Being contrary: This implies a deliberate tendency to disagree or oppose, often playfully.

* Teasing: This is a playful way to annoy someone, often with a lighthearted intent.

* Irony: This is a statement that is meant to be understood as the opposite of what is literally said.

If it's more serious or argumentative:

* Contradicting: This is a direct disagreement, stating the opposite of what someone else has said.

* Disputing: This involves a more formal disagreement, potentially leading to an argument.

* Arguing: This is a more heated exchange where both parties are trying to convince the other of their point of view.

If it's unintentional:

* Misunderstanding: This could mean they simply didn't understand what you said or meant.

* Misinterpreting: This means they understood your words but drew a different conclusion.

The specific term you choose will depend on the specific situation and the intent behind the behavior.
