Section 1: What Is “Innie”?
An innie is the most common type of belly button, where the navel dips inward toward the abdomen rather than sticking out. When people talk about an innie or outtie, they’re usually referring to this inward shape versus its outward counterpart.

An innie describes a belly button that appears sunken or indented. Instead of protruding, the skin folds inward, creating a small hollow.
How It’s Used
The word innie is informal and conversational. You’ll hear it in everyday speech, casual writing, blogs, and social media—but rarely in medical textbooks. Doctors may describe it as an “inverted umbilicus,” but in normal conversation, innie gets the job done.
Where It’s Used
The term innie is widely used in American English, British English, and other English-speaking countries. There are no special grammar rules—it’s a simple noun, sometimes used as an adjective.
