Definition

Deeply infatuated, captivated, or unable to stop thinking about something or someone. A common expression of intense interest, enthusiasm, or emotional fixation, often used casually and positively.

Example Usage

I am obsessed with this new coffee shop—I've been there five times this week.

Origin

From the Latin 'obsidere' (to besiege); the psychological term dates to the 17th century, but casual usage exploded in internet vernacular.

Fun Fact

In casual speech, 'obsessed' is rarely used to indicate clinical obsession; it's become a hyperbolic way to express excitement or attachment.
