If you’ve ever overheard your child say, “That’s so cooked,” “Aura minus,” or “He’s low-key delulu,” you may have wondered whether they were speaking English at all. Welcome to the fast-moving world of Gen Alpha slang, where new words can go viral overnight and disappear just as quickly. For children and teenagers, these phrases are more than internet jargon. They are part of how they joke, express emotions and connect with friends online and offline. While parents don’t need to start using every trending word themselves, understanding what these expressions mean can make conversations with their children a lot less confusing. Here are 10 Gen Alpha words and phrases that are everywhere in 2026.
Delulu
3 Jul 2026 | 12:38
How do you teach children about money and financial responsibility?
Short for “delusional,” this word is often used playfully to describe someone with unrealistic hopes or expectations. A teenager joking that they’ll become a billionaire next year might laugh and say, “I’m being delulu.” Most of the time, it’s used humorously rather than as an insult.
Aura
Among Gen Alpha, “aura” refers to someone’s overall vibe, confidence or cool factor. If someone handles an awkward situation gracefully, friends might say they gained “aura points.” On the other hand, an embarrassing moment could mean they lost a few.
Cooked
Being “cooked” has nothing to do with food. It means a person is in trouble, completely exhausted or facing a situation that’s unlikely to end well. Before an exam they haven’t prepared for, students often joke, “I’m cooked.”
Low-key
This phrase has been around for a while but continues to be a favourite among younger generations. Saying “I low-key like this movie” simply means “I secretly” or “I actually” like it, even if it isn’t a popular opinion.
Sigma
A “sigma” is someone who is seen as independent, confident and unconcerned about following the crowd. While the term is often used jokingly in memes, many children use it to describe someone who does things their own way without seeking approval.
NPC
Originally borrowed from gaming, where NPC stands for “non-player character,” the term now describes someone who seems predictable or lacks originality. It is usually used as a joke, although it can sometimes come across as dismissive.
Brainrot
Oxford named “brain rot” one of its Words of the Year in 2024, and the term has only grown more popular since. Gen Alpha uses it to describe internet content that is so repetitive, bizarre or addictive that it feels impossible to stop watching. Someone might jokingly admit that scrolling memes for hours has given them “brainrot.”
Lock in
When someone says it’s time to “lock in,” they mean it’s time to focus completely. Students often use it before exams, sports competitions or important projects as a way of saying distractions are over and it’s time to get serious.
Ate
If a child says, “She ate,” don’t assume they’re talking about dinner. In Gen Alpha slang, it means someone performed exceptionally well, whether it’s a dance performance, a speech or simply a great outfit. It’s one of the biggest compliments in internet culture.
Mid
Few words dismiss something as quickly as “mid.” If a movie, game or outfit is described as mid, it simply means it was average, forgettable or failed to impress. It’s not necessarily terrible, it just isn’t worth getting excited about.
