look up any word, like lemonparty:
When a Uni brow connects all the way to the hairline connecting what should be two seperate eyebrows and head hair into one omnipotent hair patch on the head and face also known as forehead beard.
Evan: Hey Josh did you see that chick's omnibrow!?

Josh: Ya man, that looked like she had an upside down beard on her forehead.
