It is obvious to me that the word "getgo" is a modified form of "get-go"
, which is obviously a type of bracketed phrase, or a shortened version of the term "Get Ready , Get Set, Go!", words we have all heard at the beginning of a variety of contests requiring speed, and a universal, equal starting time for all participants. Commonly used on playgrounds. Similar to the more formal "On your mark, Get set, Go!" The very beginning of the countdown is the "get" and you can figure out what to do at "go". I arrived at this definition using common sense. -Sonny Edwards
I thought this was silly from the getgo.
