Topsy

Used across Latin America as a mildly affectionate or lightly insulting term for someone doing something eccentric or foolish. Not strongly offensive, closer to 'weirdo' than a harsh insult.

A fixed administrative or conversational phrase. 'Visto bueno' on its own can mean the stamp of approval. Used when someone in authority formally accepts a plan or project.

Borrowed from sports officiating, used in everyday conversation to interrupt and demand a pause before something goes too far. Signals that the speaker wants to stop and address something immediately.
