I am aware of that. But it's become a "thing" -- the way "yankee" entered our language.
"Yankee" was originally a slur by English settlers and governors in the American colonies against the Dutch settlers of New York, who were known for cheese making. The English called them "Jan Kees" (John Cheese). The male name for John, "Jan" is pronounced "yahn" in Dutch, and "kees" is a play on the Dutch worrd "kaas" (cheese). Thus, the Dutch were "Yahn Kees." Later, New York patriots fighting against the English would take pride in the nickname.
So, those of us who use "bigly" knowing it was originally thought by the media to be an indicator of Trump's (and his supporters') stupidity, use the word ironically, to mock the media and the snob elites. And because we won. Bigly.
“...use the word ironically, to mock the media and the snob elites.”
No, I remember when “bigly” got started - it wasn’t irony - it was a misunderstanding... people were saying it because they thought Trump was saying it - I remember the conversations. I remember pointing out that it was “big league” and getting arguments right here on FR.
Some of the memes began exactly the way you describe, such as “hugh and series”, and they are still funny to this day.
Trust me, “bigly” just isn’t very funny.
