Pi Calculus

When π, the world’s most arguably beloved or beautiful mathematical constant, weighs the pros and cons of revealing too little or too much about herself in order to maximize her universal appeal, while minimizing any negative publicity or fallout, in popular culture.
With fierce fellow competitors like e and 𝜙 watching her every move to outwit her, it’s no surprise that π is perpetually paranoid—pi calculus remains a necessary evil for her to maintain her competitive edge.

pi watch

A phrase originating from the competitive video game Valorant meaning someone is about to have a Kill/Death ratio of 3/14, or pi. Because the scoreboard shows all individual kills, deaths, and assists in a lobby, when a teammate is doing very poorly they will be on pi watch.
Bro please let me get the last kill, I'm on pi watch.
