Pi Machine

An automatic tattoo machine found in some posh shopping malls, which has been engineered for demanding geeks who have little faith in an often-error-prone, math-anxious tattooist in accurately designing the number π.

After inputting the typeface and size of the tattoo into the pi machine, Jack waits anxiously, yet excitedly, for his body art.

Working Out Pi

When both professional and amateur mathematicians worldwide go beyond calculating the number π to billions of digits to often set up world records—their effective algorithms or methods or formulas used to achieve these high-precision calculations also directly or indirectly help usher in new developments in mathematics.

The mathematical brethren’s quest for working out pi is like MAGA patriots doing all they can to ensure that their cult leader gets reelected by any means, legal or not.

Pi Prank

Some silly, reckless, or deadly act underperforming or poorly motivated students perform on their oft-mean teacher on Pi Day, be it for fun, malice, or revenge—when these rowdies or troublemakers want to get even with adults on this most popular date in the math calendar.

Playing pi pranks like throwing a whole pizza at a teacher’s face and ordering a cicadas pizza for the math HOD is often a paying-back time for rogue students to humiliate the teaching staff.

Pi Velocity

The ability to quickly and effectively come up with new and creative ideas on or about the number π that are both useful and practical.

Pi velocity measures one’s capacity to produce the most number of pi results in the least amount of time, which occurs when there are minimal creative barriers and sufficient time spent on the math project.

Pi

Some fuckass guy who wears rectangular glasses and his value is circumference divided by diameter. He's gay but somehow he gets all of the girls. He has IBS but who even gives a shit (no pun intended). Everyone wants to integrate the area under his curves and he sometimes wears a Hatsune Miku wig, which turns him into Irratsune Piku. He is so fucking cute that you would definitely wank to him and buy a Fumo of him (not sponsored by ZUN). He plays Touhou Project and his favorite character is Reisen, aka that fuckass bunny girl who uses wavelengths physics type shit. He knows Naomi.

"bro i just learnt about pi in trigonometry class"
"omg pi is in the fucking whiteboard and all of the girls formed a CIRCLE around it"
