1. A symbolic language that uses shared conventions to compress ideas, relations, or structures into reusable units that can participate in further expressions, operations, or relationships.

The meaning of a Yaku is resolved within a context or field: the same symbol may mean different things in different contexts, as long as the relevant convention makes the meaning clear.

2. A symbol, term, or locally defined expression used in that language. A Yaku may be widely shared, such as =, ∑, or ∈, or created locally for a particular problem, document, or community.

Think of established Yaku as shared libraries and locally defined Yaku as macros. Mathematics is one of the largest and oldest ecosystems built from Yaku, but Yaku can also appear in physics, programming, music, diagrams, and other systems of structured expression.

Short for the Japanese 約語 (yakugo). 約 (yaku) carries meanings related to binding, agreement, summarizing, and compression.
“E = mc² is tiny, but it activates a huge shared library of meaning. That’s Yaku.”

“No standard symbol for this yet. I’ll define my own Yaku.”

“Without knowing the field, you can’t tell what m means. Yaku gets its meaning from the convention it is connected to.”

American Feelings Yakuza 

"feelings yakuza" is an internet slang term referring to "those who turn their personal discomfort into a social evil and try to erase the target completely". It has been used in proship/antiship discourse.

Typically, Americans will harass Japanese artists for being proship or pedophiles for what they draw. It's a concept that may be difficult to understand in Japan, where all fictional depictions are allowed, it's not good to insult someone's work, and people are looked down upon for not being able to distinguish between fiction and reality.
"I got a message from an American talking about proship"
"Don't worry about it, those are just American feelings yakuza."

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.
