Back in season two Buffy some how saw Spike and Dru doing some type of fancy Victorian Era dancing.....waltz or something like that(Sorry but I have NO clue on dancing styles lol)

During season six Buffy remembers this and in feeling jealous over it wants Spike to teach her how too do the same dance. Only problem is not having been raised in that era like Spike and Dru were Buffy has a hard time picking up the steps/moves. This frustrates her too no end.......the fact Spike mentioning that Dru was better at this then she is gets him in some serious trouble with Buffy lol.

Buffy ranting to Willow or someone about how is it that she can learn twenty different fighting style in one weekend but can't figure out some stupid simple foot moves would be funny.
