Delulu
A playful shortening of "delusional" that describes believing in your dreams with over-the-top confidence, half as a joke and half as genuine self-belief.
Delulu started out in K-pop fan communities before growing into a whole generational motto: "be delulu until it comes trululu." It's a mix of self-mockery and a nudge to hold on to your ambitions without flinching.
In practice, it shows up when you picture a big win before it happens, or act as if the opportunity is already yours. The lovely part is that it breaks through fear and hesitation and feeds a little boldness. But balance matters: healthy delulu pushes you to try and to work, not to run from reality. Let it be confidence fuel, never a substitute for the real steps.
