Glabrous - word of the week

Somehow this word is slightly onomatopoeic, it means "free from hair or down, smooth". I am more familiar with its antonym; hirsute. In the school holidays when I was about 14, I was attempting the Telegraph quick crossword, the clue I was considering was "hirsute appendage".
"Dad, what does hirsute mean?"
"Hairy......how many letters?"
"Blank-e-blank-blank-blank".
"Beard", he said. (Although it had fit, penis just hadn't seemed right).

The various glabrous appendages I had when young, all seem to have become hirsute ones.
