Male dromedary camels have an organ in their throat called a Dulla…like a large pink tongue…they extrude it to attract females and assert dominance. Comments…So, a mouth penis…Attracting chicks with a throat scrotum…Serves the same purpose as a Porsche, got it!…But can a Porsche dangle?

I had a hard time finding the Arabic origin of the English word Dulla, knowing that transliteration is often imprecise. In Wehr, I tried Dalaqa, To Spill, Pour Out (Liquid), and Dalaha, To Go Out of One’s Mind Crazy in Love, and Dalw, To Let Dangle, and finally, Dala’a. In English I’d heard it called, incorrectly, a Flaming Grimace, which later I learned to be a Flehmen [in German, To Bare One’s Upper Teeth] Grimace, among equestrians known as a Horse Laugh, related to a Dulla as a similar sexual response, but funny rather than revolting, more Mr. Ed than Dirty Old Man.
