Delulu
Teen slang, explained for parents.
What it means
Short for "delusional," used affectionately. "She's delulu about him" = she likes him way too much. Can also mean having unrealistically optimistic hopes. Used warmly between friends, not as an insult.
How to bring it up with your kid
No action needed. Just affectionate slang. If anything, a light: "Are you being a little delulu about this?" can be a funny way to open a realistic conversation.
