A friend who encourages you to leave the house and offers support when you're not certain you want to go out and mix on a crowded dance floor.
Martha was reluctant to go out in the rainstorm to get to the blues dance, but her wingdancer Josh managed to entice her out that evening by telling her how many people had missed dancing with her.
A wingette is similar to a wingman, but a chick version. Someone who is a wingette is always a great friend, who strives to set up her friends and make them look good. A wingette has a fantastic personality and is a rare, precious type of human being that should be treasured by everyone she knows. Like a best friend, but better. She helps point out stupid things you're doing and drives you home if you happen to have too many tequila shots or something of that nature.
"You hittin' the club tonight?"
"Yeah and my wingette is gonna help me reel one in."
