If there's any gap between the two tumbler lips, trickle warm water into that area. The water may act as a buffer and lubricant. Wiggle the two tumblers in opposing directions. You could also submerge the two tumblers in warm water (dishwater worked for me,) and try this same technique.
Set the outside one in a pot of steaming water on the stove for a bit, remove, and quickly fill the inner one with ice.swirl around for a second or two, and tug!

How do you separate plastic restaurant cups? They were washed and stacked together now they won't come apart.

RE: Separating Plastic Drinking Cups
Put them in the freezer and after they are thoroughly frozen try carefully pulling them apart. (12/22/2008)

You can try filling the inside one with cold water and dipping the outside one in a sink or bowl of hot water. The heat will expand the outside cup. The cold will contract the inside cup. It should be enough to break the seal. (12/29/2008)

The fastest solution might be to use your blow-dryer on the outside cup while trying to loosen the inner cup(s), which might take another person helping you. (12/29/2008)
