: What is the origin of "humdinger" which is used to imply a "big deal" or some sort of extravagance?
According to Merriam-Webster Online:
Main Entry: hum·ding·er
Etymology: probably alteration of hummer
Date: circa 1904
: a striking or extraordinary person or thing
The definition for hummer is just "one that hums", but I am not sure what that has to do with it. The American Heritage Dictionary lists the etymology as "unknown".
