Skibidi, Delulu, and more Gen-Z meme words added to Cambridge Dictionary

The Cambridge Dictionary has added numerous words and terms popularized by Gen-Z memes and internet culture to its list of recognized words.

So far in 2025, over 6,000 words have been added to the compendium and, while many are unremarkable, a portion have been sourced directly from internet culture, specifically social media sites used primarily by younger generations, including Instagram and TikTok.

The most notable words added include terms like skibidi, broligarchy, inspo, and delulu. While some of these, in the case of the latter two, are shorthand for existing words – inspiration and delusional – others have definitions that aren’t immediately obvious.

The most notable new entries and their definitions, as described by Cambridge Dictionary:

Cambridge vs. Oxford English Dictionary

The Cambridge Dictionary adds new words to its database based on their consistent use in everyday life, including social media. It relies on the Cambridge English Corpus, a huge database of over two billion words, to decide which terms to add.

Conversely, the Oxford English Dictionary adopts a slower, historical approach. Words usually need a longer track record in literature or formal writing before being added, which means slang and internet-born terms often appear there much later than in Cambridge.

That being the case, there’s every chance all of the words above will eventually make their way into the Oxford alternative, but for now, they have yet to be recognized.
