Porno, pr0n, peep shows...You get the idea.

An etymological note: An "X" rating used to mean a film wasn't rated. (In fact, one X-rated movie, Midnight Cowboy, won an Oscar.) Pornographers got hold of the X in the 70s, and soon the X became associated with ill-repute. XXX is just a way of advertising it.
I'm probably the last user on the planet who hasn't seen Pam and Tommy's XXX video.

...means Amsterdam.

(Old city crest has red shield with black stripe and XXX.)

According to some it's the source of the porn usage, meaning "this is the dog's bollocks, it's from Amsterdam".
XXX is embossed on the suggestive meaty bollards which line every street. They're called Amsterdammetjes or little Amsterdammers.

1) Used instead of 'i love you,' it stands for the three words. Is used if a person its too lazy to write 'i love you' or can be used on a text message if there is not enough space.
For Example; instead of 'ok talk to you soon baby i love you'
it would read 'ok talk to you soon baby xxx'
