1. An immensely unattractive woman who is ogreish in appearance and/or behavior(Usually both).
2. Any woman who is so heinously unattractive that one is forced to recoil in horror and utter a raspy and pained, "Whaaaaaaah!" (Sounds like Sylvester Stallone in "Rocky" calling for Adrianne)
Origin: Comes from the contraction of "Whoa! What an Ogre!"
"Sam certainly is a Whoagre"
"You're so ugly that not even a Whoagre would date you!"
