yar·mul·ke /ˈyäməlkə,ˈyäməkə / noun = a skullcap worn in public by Orthodox Jewish males or during prayer by other Jewish men. Jews of Eastern European descent (Ashkenazi Jews) refer to it as a yarmulke (a Yiddish word), but it's also called a kippah by others.
Why am I telling you this? Because Iva and I were chatting in our Circle@Crown Café yesterday when we noticed an elderly man wearing a yarmulke with Trump's face on it, bigger than this example I found online. I looked it up when I came home, because I couldn't remember how to spell "yarmulke."
