William James beat you to it:
“[The young William James] wrote “conversash” for “conversation,” “orflings” for “orphans,” “Bosting” for “Boston,” called his father’s new book “Substance and Shadder,” called Potsdam “Potsd-m,” said “suspish” for “suspicion,” “condish” for “condition,” could call an acquaintance “the very Poetry of general imbecility”…
It goes on for a bit more. But this is like that 19th century lolcat that somebody dug up. I hope there isn’t a similarly horrible backstory to William James using slangy abbreviations.
