I overheard this at work. Can't remember who said it, but the funny stuck with me. It is a play on "talking dirty" and right on the spot for me, as I was nerdy, before nerds were cool. And I love puns so much. I created the text image using font from Adobe Photoshop. It is a png image, so you can replace the background image with one of your own or delete and use a background color from Zazzle.
