Toucas are plastic caps you put on your head to take baths wihtout getting hair wet. Weird choice of a name for such an interesting tool.

I think that's in Portuguese? Touca is also the name of a bird (Toucan) in Farsi.

I wanted a name that is easy to type on the command-line (since that's the interface for many users), easy to pronounce, and somewhat meaningless in English. Touca was the best I could think of. :)
