Douche

One of the things I like to do as I travel the world is to educate people about America. I try to bring a fair impression of my country to those who might have been misinformed. For example, my poor Englishman friend had no idea from where the term "Douche Bag" originated.  

I told him about the erroneous lady-cleansing trend in the 1970's and '80's and the plastic and the soapy water and the tube and the whole bit. And I told him you're really not supposed to do it.

Then I told him the story of the time when my brother found my mom's *ahem* non-disposable *thing* and brought it to the dinner table when we had company:

"Mom. Mom. Mom. Mom. Mom. What is this thing?"

"Aah! Pete! Put that away! I'll tell you later."

"No, Mom. Mom. Mom. Mom. Just tell me now. Just tell me now Mom."

(With clenched teeth:) "Pete put that thing away, now! I'll tell you later."

"No, Mom. Mom. Mom. Mom. Just tell me now. Just tell me now Mom."

"PETE!"

(My poor mom had it at the top of our linen closet for years and probably got it free after having a baby and never used it.)

Another acceptable definition of the word "Douche": 

The sound your mouth should make when you're pantomiming punching something, usually in twos. 

I forgot to tell the poor Englishman about the song "Summer Breeze, makes me feel fine..." (you know the one) and how I sang along at the top of my lungs at work, except I legitimately thought the words were "Summer's Eve...". Or maybe I didn't forget. Maybe Ross was giving me the silent "shut up" and maybe the poor Englishman had changed the subject twice already.

See? Educating the World. The poor Englishman probably only previously knew this definition I found on the Internet:

An individual who has an overinflated sense of self worth, compounded by a low level of intelligence, behaving ridiculously in front of colleagues with no regard to how moronic he appears.
