It's goatse.cx, and the probably intentional similarity to the words "goat sex" gave me pause the first time I saw the link. Note that it does not actually depict goat sex, but don't click on anything related to it anyway.
I know ... I just wanted to avoid posting the "full address"
ever notice this similarity?

Warning: other things that you should really avoid googling: lemonparty, tubgirl, and under no circumstances look for the "Mr. Hands" video ...
