"[So and so] [did something] propissively."
Me: Huh? WTF is propissively? Is that like permissively? Propitiously?
Turns out: "on purpose." The word you're looking for there is "purposely." Or "purposefully." I know I am a total fucking English grammar nazi, but...propissively?? And he uses it All. The. Time.
Help. How do I gently, non-confrontationally, non-aggressively tell my significant other that he is regularly using a "word" that doesn't actually exist in the English language?
