Guilty

A dark, contemptuous way of telling someone you want them out of the picture entirely. More cutting than a simple insult because it implies the speaker does not care what happens to them.

Used as a threat meaning someone will face serious consequences, not necessarily literal death. Parallel to the English 'you're dead'.

Strong, contemptuous expression of total indifference. Importar una mierda is the core pattern; the subject and object can vary (me importa, le importa, etc.).

A firm, emphatic refusal or denial. Works across formal and informal registers. Equivalent in force to 'under no circumstances' or the colloquial 'no way'.

Literally 'do us a favour', but in confrontational contexts it is sarcastic and dismissive, meaning the speaker wants the other person to butt out or disappear.
