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.

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