my cock slipped in her ass stories

That's an odd situation. Maybe you were in a hurry and the clock was in your hand while you were near her backpack, and it accidentally slipped inside. It could have been a small alarm clock or a pocket watch.

I'm not entirely sure what you mean by 'cooking slipped in her casserole'. It could be a very unique or accidental situation. Maybe you were trying to transfer some cooked ingredients into the casserole dish and it accidentally slipped in an unexpected way.

No, it is not a common phrase at all. I've never come across it in normal conversations, literature, or general language use.

This is a rather vulgar and inappropriate expression. If we break it down literally, 'cock' can refer to a male chicken or be a vulgar term for a male sexual organ, and 'up my ass' is an extremely inappropriate and vulgar description. But it's not a phrase that should be used in polite or general conversation.

This phrase is very difficult to interpret without more context. 'Cock' could refer to a rooster perhaps in a very strange context related to a'spooning story' which might be about people lying closely together like spoons. But it's all very ambiguous.

There could be many interpretations of such a phrase. Maybe it's about some comical or absurd situations where things go wrong in a very extreme way. But again, without clear definition, it's just speculation.

Call for medical help if she seems to be in a lot of pain or has difficulty moving. Make sure she is comfortable while waiting for help.

Not at all. Whether it's academic writing, creative writing, or even casual writing like a blog post, this phrase has no place. It goes against the norms of good writing which include using clean, appropriate language that doesn't shock or offend the audience.

Definitely not. FM stories are often listened to by different people, including children and families. Using such offensive language would not only violate good taste but also might lead to negative impacts on the listeners. We should promote positive and clean language in all forms of media content.

Perhaps in some extremely avant - garde or underground literature there could be something related, but this would be very hard to find as it goes against the norms of most literary works which tend to focus on more common themes like love, conflict, and self - discovery rather than such a strange and unorthodox concept.
