* Defiance: When someone is asserting their authority or standing by their decision, even if it's not popular or logical.
* Stubbornness: Implying that they don't need to justify their actions, they simply decided something and that's that.
* Power: The speaker feels they have a right to make decisions and others should comply.
Example:
* "Porque dije que no se puede ir." (Because I said you can't go.)
Note: The phrase is usually used with a slightly aggressive or even arrogant tone, highlighting the speaker's dominance.
