Turkish for "cunt" is "am", not "um". It's pronounced the same as "arm" in non-rhotic English. Me and my girlfriend were once in north-east Turkey, staying with a family whose little girl was keen to learn some words of English. Marion tried to show her the words for parts of the body. She wanted "arm" repeated over and over again.

I saw a shop window in Prague about 20 years ago (a pharmacy, I think) which had dozens of posters stuck randomly all over the window, black lettering several inches high on a yellow background, just advertising the one-word name for a product:

WANK WANK   WANK WANK   WANK

   WANK WANK WANK WANK WANK

WANK WANK   WANK WANK   WANK

WANK   WANK WANK   WANK   WANK

WANK WANK    WANK    WANK   WANK

I never did find out what it was. (Nowadays with the British stag party industry, it would be advertising exactly what it said in English).
