Today we briefly discuss a truly ridiculous word, a word that is not really onomatopoeic, in that it does not reflect anything about the class of objects to which it refers. But it shares some characteristics that make many onomatopoeic words funny, such as that dominant "oo" sound. I am talking about the word "shampoo."
Aside from the always-funny "oo" sound, it is very easy to tease out "shampoo"'s most hilarious feature: the fact that it sounds like a term for a movie prop in a crude humour teen comedy flick. "Shampoo." "Sham." "Poo." Fake excrement? Since it's quite possible that most of these special hair care products are little more than snake oil, it seems like a very apt name to me. And the use of the world "poo", of course, makes it even funnier, because it brings out the inner naughtly little child in all of us.
That's "shampoo" for you. Millions and millions of people, the world over, douse their hair with the stuff on a regular basis. So why it is not more commonly seen in its humorous aspect? Shampoo!
