Facebook Faux Pas

I don't know how familiar you are with Facebook, but there is a function on it called your "status" that most of my friends use whereby you can tell people how you are feeling, or what you are doing "now." It provides your name and then you type after your name what you want to say. For example:
Alex Robins is bored!!!!
It then gives the option for your friends to comment on your status.

Well, today I my nephew Arron had written his status as:
"off to work!"
He then had a comment left by his cousin:
"work my arse!!!!!!!!!!!!!!!!!!!!!!!!"

Now, this is an innocent little jibe between cousins, unfortunately I read the comment before the status and, due to my obvious lack of understanding of the youth of today, their complete lack of understanding and usage of punctuation (not that mine is perfect), and, I admit, my depraved mind, I instantly thought it was a sexual comment.

It was meant as:
"Work? My arse!!!!!!!!!!" (as in "I don't believe you!"), and not "Work my arse!" (as in "F**k me bigboy!").

I was laughing for quite a few minutes when I eventually worked out the intended meaning.
Trust me, I don't think I am ever gonna be "down with the kids!" I never was when I was a kid, so I certainly won't be now as I get older (and older, and older, and older).
