2013 Tumblring 

Verb-

(2013 tumb-ler-ing)

Back in 2013, tumblr.com was just getting popular with a younger age group, scene and emo kids, the LGBT+ community, weeaboos , and hipsters . All of these groups combinded made the website a little unstable. Anyone with an opinion would get death threats, anyone who didn't ship two male characters were seen as homophobic, and if you didn't like tumblr then you would get thousands of 13 year old trying to convince you that they know how to hack computers and kill people.

Fandoms such a homestuck , SuperWhoLock , and various different anime became the head of tumblr in 2013. This caused problems, as they often went out of control. Stories people in homestuck cosplay attacking people with buckets (as it is a reference to the comic) and girls as young as 12 sending nudes to the many different adult male actors became common, but we're brushed off by tumblr.

2013 Tumblring refers to the attitude that people had during Tumblr is 2013. Acting like Tumblr is the best and if you disagree then you are wrong. Always being hyper, out of control. and pretending that you aren't responsible for your actions. Even though the website has grown up, there are many people today who are still 2013 Tumblring.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
