At my new job, our group does a gift exchange at our holiday luncheon. It's the kind where the first person unwraps a gift, and then the next person can either unwrap a gift or take a gift from someone who has already unwrapped a gift. If a gift is taken from someone, they then unwrap a new gift. This type of exhange is fairly common, but we found that we don't know a name to call it, at least not one that doesn't make us uncomfortable. The only names we have are "Dirty Santa" and some others that just go downhill from there. Frankly, I'm fine with "We're Doing A Gift Exchange And Here Are The Rules", but is there a socially acceptable name for this activity?
