kiss-kiss-kiss. E.g at the end of a letter or email.
I once received this e-mail from a posh girl's school:

"An e-mail addressed to you has been blocked by 'PornControl', due to its obscene content. The offending content was 'xxx'."

It turned out that my friend had signed off with, "See you soon, Jenny. xxx"

(a) 'PornControl' (not its real name) was set not to protect the girls from the wicked outside world, but to protect the outside world from the obscene girls.

(b) If it detected an obscenity in an e-mail, it kept the e-mail and just sent the obscenity.

(c) There's nothing wrong with typing 'xxx'

Don't ya just love it?

1.) The common definition for highly pornographic materials. Consider any pornographic material containing "XXX" to be the ultimate...

2.) The common marking for jugs of moonshine, or other backwoods alcoholic beverages in movies, cartoons or television shows.

2.) A movie which contains the antithesis to all actors, Vin Diesel.
1.) Woah! Da'zz sum GRAET PRON! IZ XXX!!!!!11!!

2.) If it's whiskey, why do they call it "XXX?"

3.) You paid to watch "XXX?" You're stupid.
