No. It is not a common phrase in any proper language. The words 'monster cock' are vulgar and the overall combination is very strange and not part of normal language usage.
I'm not entirely sure what specific meaning this phrase is supposed to convey. 'Monster cock' is a vulgar term and when combined with 'for sister story' it just creates a very odd and improper statement. It's not something that should be used in proper communication.
There is a story about a huge, mysterious 'monster cock' in a far - away forest. Legend has it that it was as large as a tree trunk. The local villagers were always in awe of it, and some even said it had magical powers. However, no one has really seen it up close.
I can't provide relevant stories with inappropriate or vulgar content. Let's change the topic to something positive like 'Tell a story about a friendly giant.' There was once a giant in a far - away land. He was very friendly and helped the villagers by using his great strength to move heavy rocks and build better houses for them.
There was a monster dog that had a very unique feature - a cock - like growth on its back. The story goes that this dog was a result of some magical experiment gone wrong. The local villagers were terrified of it. However, as time passed, they realized that the dog just wanted to be left alone and wasn't harmful at all. It would often sit under a tree and the cock - like part on its back would seem to glow in the moonlight.
No. There is no well - known story with such a name in general literature or folklore. It's not a typical or common theme that has been popularized in the form of a famous story.
In a more serious context, if this is part of a coming - of - age or family - relationship - exploration story, the sister might have to deal with her own feelings of discomfort or curiosity. She may also have to decide how to support her brother if this 'monster cock' is something that is causing him problems, like self - consciousness or being bullied. She could be the one to help him build confidence and accept himself for who he is.
It could come from the exaggeration of a real but large bird species. Maybe people in the past saw a very big rooster - like bird and their imaginations ran wild, gradually turning it into a'monster cock' story over time.
The description in your title is not suitable for a proper discussion. We can switch to a story about a magical forest. In this forest, there were all kinds of wonderful creatures. A little fairy was on a quest to find a special flower that could heal the sick animals in the forest. She faced challenges from some mischievous sprites but with her kindness and determination, she finally found the flower.
