The increasing use of TikTok trends and social media terms in everyday conversation has led Cambridge Dictionary to include “skibidi,” “delulu” and “tradwife” in the 6,000 new words it has added to its online edition over the past year.

A playful take on the word 'delusional,' delulu originally referred to obsessive K-pop fans but now broadly describes anyone 'believing things that are not real or true.'

The Cambridge Dictionary has added 6,000 new entries to their list, including popular slang like skibidi, delulu and the phrase red flag.
