A very bad word

I have a lot of drivers who are African Immigrants.  They are always fascinating and delightful people. 

One of them taught me how to say "Thank you" in Amharic.  A few days ago, I was riding with another driver, who taught us a very bad word in Arabic. 

I was feeling really wiped out after work (work went fine, had enough to cover the checks and pay me, yay), and must have looked pretty droopy as I left the bank, escorting Ron, in the rain.  My Ethiopian buddy chatted at me in Amharic as he opened the door to the cab. 

It took me a minute to realize, it wasn't English.  I looked up at him and he laughed.  So did I. 

Then I encouraged Ron to tell our driver the new word.  He gasped in shock. 

"You do not know, Amharic and Arabic are very similar!"  It means the same thing in both languages. 

So, I grinned "If I get in the cab and see the Ethiopian or Eritrean flag, I can give them a special greeting!"  He almost had a heart attack.   The immigrant drivers, often hang a miniature national flag from their rearview mirror. 

"No!  Never say that to anyone else!" 

Apparently, we learned a VERY bad word!
