To compulsively flip through TV channels without settling on anything. It's the mindless ritual of clicking through hundreds of channels and still finding nothing to watch.

To cause such intense secondhand embarrassment that you want to disappear from the face of the earth. When something gives you cringe, it's so awkward, so painful, or so out of place that it physically hurts to witness.

To act like you're the protagonist of a movie and the whole world revolves around you. When someone's being the main character, they live every moment as if cameras are following them with a soundtrack playing.

To get emotionally stuck on someone, unable to stop thinking about them even when you should move on. It's when someone lives rent-free in your head and you can't evict them no matter how hard you try.
