In the grand scheme of things, no. But for the fanfiction itself, it could be a central and defining concept. It gives the story a distinctiveness that sets it apart from other Naruto fanfictions. The significance might lie in the fact that it challenges the readers' perception of Naruto. It also shows the freedom that fanfiction writers have to take characters in very unexpected directions, even if it's as strange as making Naruto a log worshipper.
I'm not entirely sure what it specifically means as it seems like a rather strange and made - up concept. 'Naruto' is a well - known anime character, but the idea of being a 'log worshipper' in a fanfiction context is very unusual and might be some sort of extremely creative and out - there interpretation by the author of that fanfiction.
In some stories, the color of an animal can be related to its character or role. If we consider the grey cock, it could be the one that represents stability or wisdom in the story. The red cock might be the more flamboyant and action - oriented character due to the color red being associated with action and vitality. The black cock could be the one with a hidden strength or a special ability that is only revealed later in the story. But again, this is all speculation without the actual story.
I'm not sure what specific 'cock to cock stories' you mean. It could be some made - up or very specific local tales. Without more context, it's hard to say.
I'm not sure which specific story is referred to as just 'grey cock red cock black cock story'. There could be many fictional or cultural stories that might use these terms in different ways. Maybe it's a story about different colored cocks on a farm and their adventures, but without more context, it's hard to tell the exact story.
It could include how you first saw the rooster. For example, you might say 'I first saw the cock in a small farmyard. It was standing on a fence post, looking so majestic.'
This kind of story is inappropriate and promotes body shaming. Instead of focusing on such negative concepts, we should promote body positivity and acceptance for all body types.
