4 teammates (2 men/2 women) line up on one end of the court, each throw 1 ball. Your other two teammates stand at the opposite end of the court and act as "spotters". When that "inning/frame" is finished, 2 players walk to the opposite end to meet the 2 spotters who are now throwers. The 2 who stay are now spotters. First team to 7 wins that round, with several rounds in each of 2 matches, as time allows. Laid back, social format!
