This is what happens when mathematicians get bored on Twitter! The post brilliantly maps profanity onto complex number theory, suggesting that expletives follow the same structure as mathematical fields. "Fractional f-words" would be like 0.5 expletives, "absolute f-words" imply both positive and negative versions (just like |-5| = |5| = 5), and "imaginary f-words" parallel the imaginary numbers like i . The reply adds a delightful correction about norm spaces and isomorphisms that's peak math-nerd pedantry. Next time someone swears, just ask if they're using the real or imaginary component of their expletive field.
