Un peligro, una canción

Common in family and school contexts. Directed at children or young people to signal disobedience. The opposite, 'portarse bien', is equally common.

Fixed idiom. Signals that someone has exceeded acceptable limits of behaviour. Very common in arguments.

Used as a mild insult between young people in Argentina. Literally means 'goose' but functions as a playful or mildly cutting term for someone acting foolishly.

When used with an object like 'las cosas de alguien' or 'los asuntos de', it carries a strong connotation of unwanted interference, not just simple participation.

Idiomatic. Literally 'to send someone the bill', used figuratively to mean making someone answer for a past wrong or grievance.

Imperative of 'ubicarse'. A sharp, informal command telling someone to be more self-aware or to stop overstepping. Very characteristic of Argentine speech.
