Not sure how it's tainted you, but interesting subject and side-point. I know of a kid for who part of his exclusion from mainstream, just one incident among many obviously, came from shouting out in class,
"I need an effing wazz!"
Just one incident. But chucked out all the same because this didn't fit the middle class culture of schools where you put your hand up and ask to go to the toilet. Completely ignoring his cultural norm which was that, in his household, it was completely normal to say "I need an effing wazz!"
Minor derail but I thought you might be interested.
