I'm not sure there are any real legitimate or positive stories related to such a disturbing and cruel concept. It may be something very abnormal or from a fictional and dark context that is not worthy of promotion.
There was a big cock who lived on a farm. He had a habit of exploring new places. One day, he found his way into a shed where the farmer stored his old bowling balls. The big cock, not knowing what they were, started pecking at them. As he pecked, one of the balls rolled and hit a stack of wooden crates, causing them to tumble. This 'ballbusting' incident led to a lot of commotion on the farm as the animals came to see what had happened. The big cock just stood there, looking rather clueless about the chaos he had caused.
No. Such a story with the term 'ballbusting' in it has undertones that are not appropriate for a wide range of audiences. It may be okay for a more adult or very specific group that is okay with edgier language, but not for the general public, including kids and those who prefer clean - cut stories.
In a 'big cock dog bite ballbusting story', we could imagine a scenario where there is a big dog on a farm. There are some spherical objects around, like watermelons or large balls used for some farm - related activities. The dog, being curious or perhaps just in a rambunctious mood, goes up to one of these 'ball - like' objects and bites it. The force of its bite might be so strong that it causes some sort of destruction to the object, like cracking a watermelon or deflating a large ball.
