- An actor or TV personality you seem to stumble upon all the time, but always forget or never bother to learn their name.

- A celebrity who (in your opinion) doesn't deserve to be that famous. (used as a minor insult.)
- Dude, isn't that the guy from Just Shoot Me?
- Who, dude?
- You know that tall bald guy in Just Shoot Me, he's a total semibrity?
- Shit, dude he ain't no semibrity that's Brian Posehn. He's totally famous in my book.
