The most-searched British SLANG revealed – do you know what they mean?

Are you down with the kids, or beginning to show your age?

The answer may lie in how many of these baffling slang words you know the meanings of.

Experts from Unscramblerer.com have analysed Google search data to reveal the most-searched slang words in Britain.

‘Sigma’ – an independent, self–reliant person who operates outside traditional social hierarchies – tops the list, with 53,000 searches so far this year. 

Other terms including ‘bop’, ‘clanker’, and ‘6,7’ have also had Britons turning to Google. 

‘Popular slang in 2025 continues to be heavily influenced by TikTok, Instagram, gaming, streaming, Gen Z and Alpha online communities,’ said a spokesperson for Unscramblerer.com. 

‘Trends from social media spread rapidly via memes and viral challenges. Fueled by technology, our language adapts to new slang trends more rapidly than ever.’

So, how many of these slang words do you recognise? Scroll down for the full list of meanings.  

For the study, the team first used Google Trends to discover the top trending slang terms from 1 Janaury – 29 September. 

They then used Ahrefs to find how many times each word had been searched. 

‘People will hear or read slang terms and search for the meaning of the term (example ‘mogging meaning’),’ the team explained. 

‘Ahrefs shows many variations of meaning searches like ‘slang’ or ‘trend’ (example ‘mogging slang’) and similar keyword combinations (example ‘what does demure mean’). 

‘We added up 150 search variations of top slang terms.’

Their analysis revealed that ‘sigma’ tops the list with 54,000 searches, followed by ‘gaslighting’ (50,000 searches) – a type of manipulation that makes you doubt your memories and feelings.

Gaslighting was also the most–searched slang word of 2024. 

‘Sybau’ – standing for ‘shut your b***h up – is third on the list, followed by ‘PMO’, which has two meanings. 

‘Depending on the context this term refers to “Put me on” (introduce me to something new) or “p***es me off”,’ the experts explained. 

One of the most baffling terms on the list is ‘6,7’, which is being used by children in and out of the classroom. 

The phrase is particularly popular with Gen Alpha (those born between 2010 and 2024) and originates from a song called ‘Doot Doot (6,7)’ by American rapper Skrilla.

It simply means ‘nothing’ and can be used to suggest that a person is ‘average’. 

‘Mogging’ – outclassing someone else by appearing more attractive, skillful or successful – received 8,500 searches.

‘Looksmaxxing (16,000 searches) has a similar meaning that is also a trending slang word this year,’ Unscramblerer.com explained. 

Meanwhile, 4,000 people were baffled by the meaning of ‘Green FN, which refers to a guaranteed win.

‘Describes something amazing and highly desirable. Often said after an exceptional shot or throw in basketball,’ the experts explained. 

‘The term originates from the NBA 2K video game series, where a perfectly timed shot is marked by the color green.’

If you’re not Gen-Alpha, you might feel embarrassed to incorporate these slang words into your vocabulary.

However, Unscramblerer.com is encouraging everyone to get involved.

‘Slang is a fascinating and fun mirror of our culture,’ the spokesperson added.
