To every smoothbrain that responded thusly, if you only use a word in private amongst certain other people, then it feels a lot like we both know that’s a word you shouldn’t use.
Like scientists, doctors, and programmers who only use certain words in the company of their fellow practitioners? Or say any number of fan bases (think Anime, or personality-driven youtube channels) that have their own lingo?
Hilarious to call people "smoothbrain" while decrying "retard" Clearly it doesn't bother you when someone's intellect is questioned, so what's the issue?
