The article of New Yorker (November 21) begins with the following sentence under the title “Obama Goes Big on Immigration”:
For a two-term President whom his critics used to call “the speechifier,” Barack Obama has given surprisingly few memorable speeches, and none for quite a while. Sometimes his speechwriters over-egg it, and his language seems a bit stilted. -- Thursday night’s much-anticipated address on immigration -- was an extended statement rather than a full-blown speech, and it was much better for it. It was direct and to the point and it was relatively short—about fifteen minutes. http://www.newyorker.com/news/john-cassidy/obama-goes-big-on-immigration?
What does “go big” mean? Did the President make a spectacular speech? What is the single alternative word for it?
Oxford Dictionaries carries ‘Go (come) over big” as an idiom, but not “go big,” nor Cambridge Dictionaries Online shows “go big.”
Google Ngram shows that the usage of “go big” peaked in mid 1930s (0.0000020019 in 1935) and has been dwindling down to 0.0000010228% in 2000.
