A tiny room or cramped space so small that one person barely fits. In Argentina and Chile, living in a 'sucucho' is a specific economic reality — the student's rented closet, the storage room converted to a bedroom, the studio apartment that's technically a large drawer.

To take off at full speed or throw yourself completely into doing something with everything you've got. In Argentina and Chile, 'embalarse' is going from zero to maximum instantly — the car that launches off the light, the person who commits to a project without brakes.

A pimp — someone who profits from women working in the sex industry. In Argentina, 'cafishio' is lunfardo at its darkest: a word with a specific meaning, no ambiguity, and a long history in Buenos Aires port culture where the term originated among immigrant communities.

Intense sexual desire or strong physical attraction toward someone. In Argentina and Chile, 'calentura' is frank and direct — it describes the feeling precisely without the polite circumlocution other countries might prefer. Bodies want things, and calentura names that clearly.
