Cambridge Dictionary adds Gen Z slang like "skibidi", "delulu", and "tradwife" among 6000 plus new entries

The Cambridge Dictionary has expanded with over 6,200 new words, phrases, and meanings in its latest update, spotlighting internet-driven slang terms that capture evolving language trends. Among the most eye-catching additions are "skibidi", "delulu", and "tradwife."

"Skibidi" is a playful, nonsensical word from the viral "Skibidi Toilet" YouTube series. The dictionary defines it as a term that can mean "cool," "bad," or be used without a real meaning as a joke — such as in the phrase “What the skibidi are you doing?”

"Delulu" is a shorthand for "delusional," used to describe a belief in something unreal, often chosen rather than factual. The term originated in K-pop fan culture and has gained traction through phrases like "delulu with no solulu," which became a viral catchphrase—even used by Australia’s prime minister in Parliament.

"Tradwife", short for "traditional wife," describes a woman, often on social media, embracing conventional homemaker roles. The trend has gained visibility on platforms like TikTok and Instagram.

Other notable entries include "mouse jiggler"—a device or software that simulates computer activity during remote work, and "forever chemical", referring to persistent environmental pollutants.

Colin McIntosh, Lexical Programme Manager at Cambridge Dictionary, emphasized that only words with "staying power" are included, reflecting how internet culture significantly influences the evolution of English.

The surge of slang terms — from "skibidi" to "tradwife"—underscores how digital and social media are reshaping language, especially among younger generations. While some celebrate this evolution, others criticize it as dilutive, dubbing it "brainrot." Yet lexicographers argue that dictionaries must faithfully mirror current usage.
