Tanjiro is the main protagonist of the anime: Kimetsu no Yaiba (also known as Demon Slayer).
He has a scar on his head, and he's also part of the Demon Slayer Corps, and his job is to slay demons.
His journey starts off with a demon killing and eating his family, and only his sister Nezuko surviving. Nezuko turns into a demon, however, and attacks Tanjiro. After a bit, however, she stops attacking and decides not to eat him, for whatever reason.
Tanjiro is a very kind person and takes care of his sister well.
Yo you see that awesome Water Breathing and Total Concentration move that Tanjiro did? So badass!

Kamado Tanjiro 

A fellow boy from the anime Demon Slayer with an inhumanly kind and big heart. His family was murdered by demons, and everybody died except Nezuko, his sister who turns into a demon.
He joins the Demon Slayer Corps to find a way to turn his sister back into a human. Tanjiro is (without a doubt) the kindest out of the 3.7 billion people on this planet. If you know this dude and like him, your life is worth the galaxy💖.
P.S his head is harder than the hardest stone on Earth and is enough to take down a whole army with one head butt.
Inosuke: "Oi Kamaboko Gonpachiro (he thinks Tanjiro's name is Kamaboko Gonpachiro)! Challenge me to a head butt battle!"

Kamado Tanjiro: "Are you sure? Your injuries aren't healed yet... you should rest some more until you do some fighting!"

trucker's tan 

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.

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.
According to the boffins downstairs, the murderer used a serrated blade.

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.
