Una desilusión, una canción

Literally 'it is good/tasty.' In Rioplatense Spanish this phrase has extended far beyond food to mean general approval or positive evaluation of a situation, idea, or plan. The shift in meaning from 'tasty' to 'good/cool' is not obvious to learners.

A fixed phrase used reflexively (darse por vencido) to express conceding or surrendering in a struggle, argument, or effort. Not transparently compositional for learners unfamiliar with the fixed structure.

Literally 'it comes to my head.' A fixed Rioplatense expression for something suddenly occurring to someone, equivalent to 'it just hit me' or 'it popped into my head.'

Augmentative of 'bombón' (bonbon/chocolate). In Rioplatense slang, 'bombón' alone means an attractive person, and the augmentative '-azo' intensifies it. Playful and informal, not offensive, typically used between friends.

Literally 'to remove the mask.' Used figuratively to mean exposing someone's true intentions or deceit. Formal enough to appear in writing but common in spoken Argentine Spanish when discussing betrayal or manipulation.
