Girls who you are friends with and involve in your social activities, but mainly because
they are girls, and moreso for superficial
than real redeeming qualities. Often called upon to help achieve a 1:1 male-female ratio. Can also
be used in reverse, to describe males, although that is less common.
"Want to see if Liz and her friends are interested in going
"Nah we have 5 girls
already, we don't need any ratio fodder"
"She's kind of boring
but she's hot so she makes good ratio fodder"
