When a single biddy decides to go out, she enlists the help of one or more of her closest friends to play the role of "wing biddy". This is the female equivalent of the "wingman". The wing biddy's responsibilities include:
1.) Making sure the queen biddy gets some, but that it is quality
2.) Using her biddy skills to deflect attention to queen biddy
A wing biddy is selfless, charming, she drinks shot for shot with her queen biddy, but is always in control. If necessary a wing biddy will take one for the team.
Bro: "Who are you bringing to my party tonight?"
Biddy: "Just me and my favorite wing biddy"
