JK500's definitions
A person who acts like they are smart, current, and in touch with the world, but is actually clueless, out of depth, or missing the point entirely. Used as a comeback to dismiss arrogance or condescension, especially when someone uses “boomer” to label others. Not tied to age or generation—it’s about mindset and awareness.
Person A: “Okay, boomer.” Person B: “Blanker.” Person A: “What’s that?” Person B: “Someone who thinks they’re so in the know but really isn’t. Look it up.”
