Irrational Treasure

An old-fashioned exclamation of surprise or frustration, used here deliberately to mimic 19th-century pioneer speech. It is rarely used in everyday modern Latin American Spanish but is immediately understood as comic or archaic.

A mild, old-fashioned euphemistic exclamation. Like 'repámpanos', it is used in the episode to parody 19th-century speech. In modern usage it sounds deliberately quaint or humorous.

Short for the fixed phrase 'agua pasada no mueve molino'. When a speaker says 'eso es agua pasada', they are dismissing a past conflict or problem as no longer worth discussing.

Derived from 'aprovechar' (to take advantage of / to make use of). As a noun, 'aprovechado' refers to a person who exploits situations or others for personal gain without contributing. The negative connotation is strong and non-obvious from the verb alone.
