If you've been calling yourself "delulu," flexing a new "lewk," or joking about "skibidi," congratulations, the Cambridge dictionary just made it official.
Cambridge has now added more than 6,000 new words and phrases to its online dictionary, many borrowed straight from social media, pop culture, and office gossip.
Topping the list is delulu, shorthand for "delusional," defined as "believing things that are not real or true, usually because you choose to." The word, which has found loyal fans in Kenya, is often used when someone decides to ignore reality in favor of fantasy.
In March 2025, Australian Prime Minister Anthony Albanese used the Gen-Z phrase "delulu with no solulu" in a speech in parliament. "Internet culture is changing the English language," noted Cambridge Dictionary's Lexical Programme Manager, Colin McIntosh.
