You're missing the joke. It was an old Main Board thread on "favorite sects positions" and some turnip submitted "reverse cowgirl with tits in my face", not contemplating the absurdity of the position. It became an instant Main Board legend ... well, after 30 pages or so of eviscerating the dude.
It was probably the 2nd best sects thread in tMB's history (IMO), and it's waaaaaay behind the thread where some dude tried to massage his own prostate. I think my abdomen cramped up from laughing so hard that night whilst reading that thread. If I still had tMB access, I'd love to track it down and see it all in it's glory again.
In it's prime, tMB was the wild wild west. Great times.
