The Cambridge Dictionary isn’t just about old-timey words anymore. In 2025, they added over 6,000 new words, and a lot of them come straight from the internet, social media, and meme culture. Some of the words have people scratching their heads, but they’re definitely part of how people are talking online today.
Words That Were Added to the Cambridge Dictionary
Take “skibidi”, for example. This word comes from a viral YouTube series called Skibidi Toilet. Honestly, it doesn’t have a set meaning. People just throw it around when they’re excited, amused, or trying to be funny—kind of like saying “cool” or “awesome,” but in a totally random way. Internet culture loves nonsense like this, and apparently, the dictionary does too.

Then there’s “tradwife”, which stands for “traditional wife.” These are women who embrace classic domestic roles and sometimes share their lifestyles on TikTok and Instagram. Some people see it as a nod to old-school family values. Others think it’s a bit problematic because it can reinforce outdated gender roles. Either way, it’s become a trend that’s impossible to ignore, and now it’s officially a word.

Another addition is “delulu”, short for “delusional.” This one is mostly used in fandom communities—K-pop fans, in particular. When someone is living in a fantasy or just wildly overestimating reality, they’re “delulu.” People often use it jokingly, like, “I’m totally delulu for thinking I’ll meet my favorite idol someday.” It’s a fun, self-aware way to call out unrealistic expectations online.
But the new entries aren’t just about memes and trends. Some reflect real-world stuff too. For instance, “mouse jiggler”is a tool or software that keeps your computer active so it looks like you’re working. And “forever chemicals” are harmful synthetic substances that don’t break down in the environment—an actual problem that people are starting to talk about more. These words show that language evolves to match not just culture, but also the issues people care about.
So how does Cambridge decide what makes the cut? They rely on the Cambridge English Corpus, a huge database of written and spoken English. Lexicographers look for words that are widely used and likely to stick around. Basically, it’s not just any random slang—these are words that have actually made a mark on how people communicate.

Of course, not everyone is thrilled. Some critics think adding words like skibidi or delulu makes the dictionary feel less serious. But language isn’t static—it’s always changing, and the internet is a huge part of that. Supporters argue that dictionaries should reflect the words people actually use, and right now, that includes memes and TikTok trends.
At the end of the day, the 2025 update is a reminder that English is alive and constantly evolving. Words like skibidi, tradwife, and delulu show just how much online culture shapes the way we talk. Whether you love it or hate it, the dictionary is keeping up with the times—and maybe even giving your favorite memes a bit of official recognition.
