My stock of funny feminine Arabic names is pretty small, that one comes by way of the old '50s song "Ahab the Arab". But I don't think "Fatima" would be offended anyway. It was a Joke, Senior Ratone, a Joke.
I know just having some fun. Perhaps Shaharizad??
Remember Omar and Fatima, in this scenario, only make "tents" they don't necessarily wear them.
I on the other hand do shop at "The Casual Male".
