How do you tit wank a 6 year old? Break her shoulders.
What makes you want to portray children like that?
What? Who is concerned about that? This is just humor.
I understand you're trying to be funny and while these jokes may be funny the other people, need to understand other people may not think that way.
I still don't see why it's vulgar.
The terms that are using with children as a joke would be offensive to other people. I think if he took some time to realize what you're saying you would understand this.
