an adjective used on girls to rate them. Usually comes with the ham meter package which can detect the scale of a ham girl. 99% of the female population don't know what this means, so use freely. Most of the ham population live in a small town called Oak Harbor, WA. It's fucking terrible. The smallest thing can turn a fine ass girl into a ham ass mother fucking bitch.
It's a great cover-up for the following words:
We got so many ham ass bitches in our school!
Joe: Hey Pam, guess what!?
Joe: You're ham!
OH GOD! MY HAM METER IS GOING OFF!!
*Ham girl walking by in confusion*
-Guy walks into a group of girls-
Attention! Attention! You're all ham as fuck.
