We've all played the classic party game Taboo, to varying degrees of frustration. This is a group version with notably higher stakes in the form of presents!
Request that every member bring a wrapped gift (or two if you're working with a smaller group — the more the better!), and place them all in a pile. The group picks a gift and the lucky (or unlucky) participant to describe it. The person unwraps the gift out of site of the group, and then tries to explain what it is. In this version of Taboo, everyone can guess at once, and the winner gets to keep the present!
