The Cambridge Dictionary has officially added the slang terms “skibidi” and “delulu” to its online edition, reflecting the growing influence of internet culture on the English language.

“Skibidi,” a playful, gibberish word popularized by the viral YouTube series Skibidi Toilet, is defined as having multiple meanings – from “cool” to “bad” – or sometimes no meaning at all, used simply as a joke. Colin McIntosh, Lexical Programme Manager at Cambridge Dictionary, noted that such additions capture the evolving ways people communicate online and offline.

Meanwhile, “Delulu,” a shortened form of “delusional,” is defined as believing things that are not real or true, often by choice. The term, widely used on platforms like TikTok and X (formerly Twitter), has been embraced in humorous and self-aware contexts.Both words are among more than 6,000 new entries added this year, alongside other social media–driven slang and culturally relevant terms such as “tradwife,” “red flag,” “mouse jiggler” and “work wife” to name a few.
