Elif air ab dinikh!
Any seasoned traveler will make sure to familiarize themselves with what’s considered rude in other countries lest they make a fool of themselves. I learned this the hard way. When on a backpacking trip through Lithuania and Russia, I got in the habit of giving the thumbs in addition to any acknowledgement I was making. I finally caught on after the second or third day that I was essentially flipping everyone off (no thanks to all the people who let me flip them off for two or three days).
But I digress, there are plenty of insults that get lost in translation around the world and they have us belly laughing in our seats.
Chupe mantequilla de mi culo!!
