Also, Greek has smooth and rough breathing, called psilé kai daseia. Daseia
means hairy.
I looked in Eric Weisstein's World of Mathematics and found no hairy numbers.
There are, though, a Hairy Ball Theorem (the hair has to have a whorl or other
singularity somewhere) and Haar integral, function, measure, and transform (one
cycle of a square wave at a power-of-two frequency).
