A scientific term. Tumblr's Law states that when a Tumblr user directly mentions or implies that a joke is funny, the joke is no longer funny. This can be commonly done through saying that a meme is hilarious, but can also be completed through such an action as laughing. When a Tumblr User (commonly self-identified by a person with an active Tumblr account) laughs at something that could be considered humorous, every living being within a 5 mile radius instantly stops feeling joy for a short time. After this event, the joke is no longer funny, and it can no longer be referenced. The only potential Tumblr Users then have for humor is in creating jokes, but hopefully it is not attempted on Tumblr.
