AskNott, I’m sorry, I’m pretty sure they’re both pulling your leg. I studied Classical and Standard Arabic; the spoken dialects are so altered that they’re almost different languages, and I would need special study to understand them, or else live where they’re spoken. It’s like if you had studied only Latin all your life, and then tried to understand Italian. You’d sort of understand less than half of it, and the rest would be baffling. Arabic diglossia is like that. I don’t recognize whatever dialect the first one is in, if it’s real. I swear it looks like (someone’s idea of) a joke.
The second one is more like an exaggeration than a fabrication. al-Latîf is one of the 99 Beautiful Names of Allah. It has been translated as ‘the Subtle’. The vocative form yâ Latîf is used for direct address to God. The word latîf also means ‘thin, fine, delicate, dainty; little, small, insignificant; gentle, soft, light, mild; pleasant, agreeable; amiable, friendly, kind, nice; civil, courteous, polite; affable, genial; pretty, charming, lovely, graceful; intellectually refined, full of esprit, witty; elegant’. Hans Wehr’s dictionary translates the attribute of Allah al-Latîf as ‘the Kind’. Hans also tells us:
yâ Latîf — “O my God! Good heavens! For goodness’ sake!”
al-jins al-latîf — “the fair sex.”
If Kesey wasn’t just making stuff up (hey, he’s a writer, writers make stuff up, and Kesey had a vivid imagination coupled with a gnarly sense of humor), maybe the reference to a “garden” is an allusion to a widely-known story in which a character says that, and it becomes a catchphrase. For example, Dopers keep using catchphrases from TV shows and movies. I do not think that catchphrase means what you think it means. Well, this is just my WAG. I don’t know what Kesey was thinking. But I suggest if your version works so well as a pickup line, just keep it, don’t tamper with what works. Until you try it on another brainy female Arabist, who will laugh at you. 
If anyone is surprised that Allah is called “dainty, pretty, lovely, graceful” as though She’s a girl, well you’d be surprised. The femininity of Allah is one of Islam’s best kept secrets. Read Laylá and Majnûn.
