Estar que trina

to be furious; **to be furious**; **to be fuming**; **to be livid**; **to be hopping mad**; **to be boiling with anger**

Estar que trina means to be extremely angry, furious or very annoyed.

It describes someone who is visibly upset and unable to hide their irritation.

• is furious about something
• has been treated unfairly
• is extremely irritated
• is complaining angrily
• has completely lost their patience

The expression comes from the verb trinar, the sound made by birds.

Although birds often sing pleasantly, they also produce loud, repetitive calls when defending their territory or reacting to danger.

Spanish focuses on these agitated calls, comparing an angry person's constant complaints or outbursts to an excited bird's frantic chirping.

The expression usually refers to visible anger.

Someone who está que trina is often:

• complaining,
• protesting,
• shouting,
• or clearly showing their irritation.

It is frequently used in newspapers to describe reactions by politicians, coaches or supporters after controversial events.

Spanish has many colourful expressions for anger:

• Estar que trina → to be fuming.
• Echar humo → to be steaming with anger.
• Subirse por las paredes → to be climbing the walls.
• Perder los nervios → to lose one's temper.

Among them, estar que trina is one of the most vivid because it compares an angry person's outbursts to the frantic calls of an agitated bird.

Do not translate the expression literally.

English speakers would never say:

He's chirping.

Instead, use expressions such as:

• He's fuming.
• She's furious.
• He's absolutely livid.
• She's hopping mad.

The emphasis is on strong anger, not on making pleasant sounds.
