My Sister, My Sitter

Widely used in Latin American Spanish to mean utterly destroying or defeating something or someone, whether physically or figuratively. The image is of something shattered into tiny fragments.

Refers to causing loud disorder or excitement, often used when someone arrives unexpectedly or acts in a disruptive way. Common across Latin American Spanish.

Used as a pointed reproach when someone reacts to a situation with exaggerated immaturity or petulance. The force of the insult depends on who delivers it and to whom.

Used after describing using something to its absolute limit, implying the object is returned in a worn-out or barely usable state. Humorous in tone.

Borrowed from the political concept but used here as deadpan humor: invoking a high-minded principle to justify simple refusal to cooperate. The comic effect comes from the mismatch between the grand phrase and the trivial situation.
