Brain rot

Mental dullness from consuming too much low-quality content

EN
Example

I've had total brain rot today-I've done nothing but scroll TikTok and now I can't focus on work.

When to use it

After spending three hours watching random short videos, you complain to a friend that you can't think straight anymore.

What it means

Literally your brain "rotting," like food going bad.
In practice it means you feel mentally mushy or unfocused because you've been binging too much low-effort, addictive content (doomscrolling, trash TV, endless shorts). People also use it jokingly to describe silly internet obsessions or memes that take over their mind. It's common online, especially when talking about social media habits and "algorithm" content.

Don't confuse it with

"Brain rot" does not mean a medical memory disorder, a complicated maths problem, a loud argument. It specifically means "Mental dullness from consuming too much low-quality content".

Why Learn British slang with mates?

🎯 Why Learn British Slang

If you're an American or non-British English speaker planning to visit, work, or study in the UK, you'll quickly discover that British English is far more than just a different accent. British people use completely different vocabulary for everyday situations, speak in layers of irony and understatement that confuse outsiders, and rely on cultural references and slang that traditional English courses never cover. Learning British slang transforms you from a confused tourist to someone who actually understands British conversation, humor, and culture.

👤 Who This Course Is For

This course is perfect for intermediate English learners (B1-B2 level) who want to understand British media, prepare for UK travel or relocation, work with British colleagues, or simply love British culture and want deeper access to it. It's designed for Americans confused by British vocabulary, international students preparing to study in the UK, professionals working with British teams, anglophiles who want to understand British TV and films authentically, and anyone frustrated by the gaps in their understanding when Brits speak naturally. You should have solid English foundations and be ready to explore regional vocabulary, cultural humor, and informal registers.

📚 What You'll Learn

Master essential British expressions used daily across the UK. Learn common reactions like 'gutted' (disappointed), 'chuffed' (pleased), 'knackered' (exhausted), and 'gobsmacked' (shocked). Understand uniquely British phrases like 'Bob's your uncle', 'taking the piss', 'couldn't be arsed', and 'lost the plot'. Discover British vocabulary for everyday items that differ from American English — what Americans call 'fries' are 'chips', 'pants' are 'trousers', and 'trash' is 'rubbish'. Learn how to navigate British pub culture, workplace banter, and social situations with appropriate vocabulary and cultural awareness.
