I have friends who use the term "drop kick" as a joke. There a saying which involves a "Kirkby kiss", it means to head butt someone (Glasgow says the same).
We all have different personalities and background.
In my family, we swear, not at each other, but generally (we are sensitive to where we are).
I will use jokes amongst my friends and my now adult children, that I wouldn't of, in front if my Nan, or people I didn't know would accept my SOH.
I don't think twice about some things, some of my friends would say and would laugh, if other friends said the same, I would be worried, as it would be out of character.
Some if us are "rougher", for want if a better description. I cannot undo my childhood and my environment and when around some people, I do not want to change, or change them.
Likewise some people use FB as though they are having a private conversation to trusted friends.
My Son in law used to tell my youngest he'd put her in the weelie bin, she knew he never meant it. Recently whilst having Banter on FB, he put it again.
I wonder at the extent that people over around 27 use FB, but other than that, it's no-ones business, tbh.
There are some things which I object to, jokes around sexual abuse etc, meant sexism and Racism, as you cannot use the excuse venting.
I have a friend with twins that frequently offers them for sale, or asks if anyone knows how to make her basement so they can't escape, but I never felt inclined to take it seriously.
