Tumblr Dictionary! from Tumblog-it!

Hello! I have been giving tutorials and links for everyone to help you improve the Tumblr experience, but I notice there's a lot of "tumblr words" people doesn't know about. I decide to make a Tumblr Dictionary so everyone can start knowing the most common words from tumblr.

What does re-blog means? What is a Post? and such. Please share this dictionary with anyone that is learning the Tumblr world. Remember to credit Tumblog-it for it!
