There is a restaurant we passed by in HÃjar, Spain called 'Restaurant Arse'. So, of course (though non-native Spanish speakers) we had to ask Kagi Translate (we are subscribers to Kagi) what "arse" might mean in Spanish.
This attached is not even close to the answer, and the examples appear fabricated, because it is not (afaik) a Spanish word, slang or otherwise. (I have checked various other sources!)
Is there a glitch here? 
Fpr Translate to tell me the word did not exist (other than perhaps as a name) in Spanish.
