A bastard deviant child of Socialism and Self-Victimization where one claims they support the building of a socialist state, without providing the means of doing so. A substantial amount of the ideas used to support Tumblrism were conceived during collective conversations on Tumblr (particularly Tumblr safespace).

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.

A form of escapism from reality by using Tumblr all day and night.

When somebody is addicted to Tumblr. Meow. The thought that your life wouldn't be right without it.
