Female Once Over 

When two girls or women meet each other for the first time then they proceed to look each other over to see if the other is a threat socially or economically.

Ya, Julia and I met for the first time last night. We gave each other the Female Once Over. I figured I was prettier than she was, and she had more money than me so we got along fine.
