Top Definition
A short, philosophic thought, usually limited to one or two sentences, posted on tumblr. They tend to relate to life - typically, the bloggers's life.

Ex.
"I don’t do it because I like it. I do it because I tell me to."

They could easily be facebook statuses as well. However, Tumblr is generally a better emotional dump, because your grandma isn't there to make awkward comments.
I was lying in my bed last night, trying to fall asleep, but a sudden burst of inspiration hit me and I had to get up for a few seconds to post another tumblethought.
