Big-ass forehead 

The kind of forehead that few people have because most people have small-ass foreheads. People who have them are often made fun of by dense failures of society who have nothing better to do with their free time and refuse to see their own (obvious) flaws.

Damn, that girl sure has a big-ass forehead.
