tumblelog 

A tumblelog is a variation of a blog, that favors short-form, mixed-media posts over the longer editorial posts frequently associated with blogging. Common post formats found on tumblelogs include links, photos, quotes, dialogues, and video. Unlike blogs, this format is frequently used to share the author's creations, discoveries, or experiences without providing a commentary.
The term "tumblelog" was coined by Why the lucky stiff in a blog post on April 12th, 2005, while describing Anarchaia.

tumblecock 

A rolling ball of cock. Used as an insult. When someone is beyond just a cock, they are so much cock that it can't stay in one place.

To use the word and the idea best, you need to just yell the word into the face of the tumblecock.

"Bob is a tumblecock!"
"Yea he is, watch this" *walks over to Bob and leans into his face* "TUMBLECOCK!"
