Mistaken spelling and pronunciation of the words "Big League" as used by Donald Trump as he describes something that is "immense," "top drawer," or merely "very important." He can use the phrase as both an adverb and as an adjective.
Trump: "I'm going to cut taxes big league (not bigly), and you, Hillary, are going to raise taxes big league.

Trump: My policies on immigration will drive big league (not bigly) enhancements to National Security.

A corruption of "big league", most commonly used by people trying to mock Trump's stupidity, while only managing to highlighting their own deafness, and possibly the real physiological effect of *wanting* to believe something is true - even at the cost of sacrificing your own powers of judgement.
Donald Trump: "I'm going to cut taxes, big league - and you're going to raise taxes, big league!"

Deaf libtard: "OMG did he just say bigly?!"

Sensible person: "No, he clearly said big le-"

Deaf libtard: "OMG what an idiot! He thinks bigly is a word! And how dare you use the word "deaf", you misogynist! That's racist!"

Donald Trump's brilliant and superb way of describing something that is really, really yuge.

Why should anyone be confused? Mr. Trump is saying two words - "bigly" and "big league" - at precisely the same time.
"I’m going to cut taxes bigly/big league, and you’re going to raise taxes bigly/big league. End of story,” Donald Trump said."
