We all have accents pertaining to where we either were Born and / or have lived for a certain amount of our lives...
Frank and his mates used to Do Banter about my accent when I used to meet them in Laaaandaaahn for Arsenal games (before he - understandably - stopped going to Arsenal)..
I can only imagine the Carnage of the Banter if a load of us were to actually Meet up for a game (

Ooooh! Now There's An Idea! ) - The Pre-match drinking etc - The piss taking of each other and maybe there might be some banter about accents, I don't know... But the banter above on the Chinese person/s speaking English was in
No Way intended to insult or put down said persons. I only know a few words of Cantonese (taught to me by a friend who works as a translator) and she always laughs when I (try and) speak Cantonese, because of my British inflections on those words and phrases.
Also there is a difference between online/forum banter / Mickey taking and actually doing such a thing to someone's face - Something none of us would do.
I dunno, maybe Clummo's right... But also to call someone an Arsewipe is also purposely intended as an insult ...Maybe Arsewipe in Chinese sounds or comes across better... I dunno
It just seems it's got to the point where if we ever so slightly veer off the PC highway we get called on it.... But when I visit friends etc who live in other parts of the world - They will often say something about my accent and I just say "What Accent?"
Some us work in environments where the humour / banter can sometimes appear "dark" to outsiders, but it is fully understood that it is ONLY for the purposes of being able to laugh and make light of sometimes HORRENDOUS situations and experiences....
The thing is there. are some people who have never seen or worked in the Underbelly of life, so when they meet it and those who are in it up to their eyes every day they are shocked by the humour... Often it can be a way of coping and dealing with something that otherwise can
Haunt you.
So for now I shall just say: "Shàng āsēn nà".
