Oasis

An intensified version of 'qué' used to express strong irritation or disbelief. Coño on its own also functions as a standalone exclamation across a wide range of emotions.

A very common expression meaning to make a serious mistake or cause a problem. Used reflexively: 'la he cagado' means 'I've screwed up'. Direct and expressive without being the most extreme register.

A strong expression of total exasperation. Cojones literally refers to testicles but appears in many fixed idiomatic expressions. Interchangeable with 'estar harto' but far more emphatic and coarser.

In this emotional context, 'pillado' (from 'pillar', to catch) means someone has fallen hard for another person and cannot get them out of their head. Can also mean 'caught' in a more literal sense, so context is key.

The standard colloquial expression for infidelity in a relationship. 'Los cuernos' (the horns) is a classic symbol of a cuckolded partner across many Romance languages and cultures.

Despite its literal components, this is an enthusiastic positive expression. Tone is key: used to praise, cheer on, or express that something is going extremely well.

Very common among younger speakers. Can express positive amazement ('flipas si ves esto') or disbelief/shock. Also used ironically.

Used as an exclamatory construction, often followed by an insult or teasing word: 'serás perra', 'serás tonto'. The future tense here does not refer to future time, it expresses exasperated or affectionate disbelief about a person's character.
