'Game of Thrones' Creator George R.R. Martin -- I'm NOT Obsessed With 'Weenies' ... I LOVE BOOBS!

George R.R. Martin says "South Park'" got it all wrong ... claiming he's NOT the wiener-obsessed old man he was made out to be ... he's more of a boob man!

The "Game of Thrones" creator decided to set the record straight at Comic-Con during an interview with Clevver News -- right after he admitted that he's never actually watched the famous "GoT" episode.

"I do have to say I've been told that my character on 'South Park' is obsessed about weenies. I have to deny this as a scurrilous rumor."

But what Martin says next is even more entertaining than watching Lord Tyrion bitch slap Joffrey.

Well, almost.
