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.
