It's on the brain 🧠💭

Meaning

This phrase means that someone is thinking about something constantly and obsessively.

Origin

Imagine the brain as a theater stage. When an idea, person, or obsession truly takes hold, it doesn't just wander through the lobby; it commandeers the main stage. It becomes the star of the show, demanding constant attention, playing on repeat, and making it impossible for any other performance to get a look-in. This vivid mental image captures the feeling of something imprinting itself so deeply that it feels physically present, dominating every thought and every moment of your mental life.
