a female with one extra x chromasome (something didn't seperate right), doesn't cause them to be any differrent from normal females, except for the fact that they have an 2 unused chromasomes rather than 1.

...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.

XXX 

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.
