If I received a dollar for every time an expletive was so much as uttered in any of the offices I have worked at in my entire career, I would probably make more money than I do from trading. (Modesty aside and for purposes of this hypothetical comparison, I am actually reasonably good at the sport of buying low and selling high, so yes that's how much swearing is done.)

Profanity is integral to the trading lexicon as much as "buy" or "sell" is, and a day without open swearing is rarer than a white Christmas in an equatorial country. Meaning, it doesn't fucking happen ever. There is no pretense or self-censorship or any stupid replacement PG-13 words like "shucks" or "freaking". You are a complete tool when you're such a big boy you almost said a dirty word.
