Definitely not. In normal English usage, we don't come across such a phrase. It might be a very specific family or individual - created phrase that has no common or widespread usage in the English - speaking world.
The phrase is rather odd. 'Ducking' might be a wrong usage here instead of perhaps 'duck' or something else. Maybe it's a family story where there was some confusion about a duck and a rooster, but this is just speculation without more details from you.
Since I don't know the exact nature of this story, it's hard to say. It might be a fictional story created by someone with a unique concept in mind. Maybe it involves a character named Mom who has some teasing - like behavior, but without more context, it's all speculation.
I'm not sure specifically which 'Mom Sees the Cock True Story' you are referring to. There could be many different stories with such a title. It might be about a situation where a mother witnesses a rooster in an unexpected or interesting scenario, perhaps on a farm or in a rural area.
We should focus on positive, family - friendly and appropriate topics for Halloween, such as spooky but cute ghost stories or stories about trick - or - treating.
Since'mom mind control cock story' is such an unusual and undefined term, it could be a local or personal story. It might be a story that combines elements of family relationships (the mom part), mind control which is a common fictional trope, and 'cock' which could refer to a rooster in a farm - related or fable - like story, or it could be some sort of code - word within a particular group for something else entirely. Without further details, we can only speculate.
It could be something like the son accidentally wearing his clothes inside out to school and the mom found out later. Maybe she had to go to the school to drop off something and saw her son like that among his classmates.
I'm sorry but this topic involves inappropriate and vulgar content. We can focus on positive, family - friendly and ethical topics like 'A Loving Mom's Adventure in Parenting' instead.
