I like it! But I don't have a tumblr so I can't like it on tumblr... I think.
I also like it, and also do not have a tumblr! (For a while I was getting confused with the acronym "PDD" being used for Privilege Denying Dude...I was like, "PDD? What *about* pervasive developmental...oh, it's an unrelated internet meme, never mind.")
Ha! I like it, too, and am also not on Tumblr, so this is the first I saw it.@fitz-clementine - that confused me too.
I ABSOLUTELY had the same reaction to the PDD acronym.
