Question: What does it mean when you say someone is the bee's knees?

Answer: The origin of this phrase is not clear, but it is usually used to describe someone who thinks he or she is superior to others. It may derive from the supposed careful bending of a bee's knees when it transfers pollen from its body into its pollen sacs. Or it may just have evolved from the nice-sounding rhyme.
