wing team

It's like that term "wing man," except that it applies when there are more than just one person helping someone out in efforts to connect with someone they don't know in a romantic and/or sexual way. It's most often used in polyamory, when multiple partners support someone's efforts with a new partner. A wing team, however, does not always consist of established partners.

When Shelly and Anneli took me out to dinner for our triad anniversary, Anneli took a liking to someone sitting at the bar. Shelly and I had played wing team for Ann before, so we had the two them talking up a storm in no time at all, with full disclosure about our triad from the very beginning. Best anniversary ever.
