Believed by non-rednecks to be an interjection. Believed to have originated in 1934 in a small town in Alabama called Mahsister(the name of the town comes from the founder who named it after the one who he liked having intercourse with most). In Mahsister, Alabama, in the summer of '34, a cat had climbed up a tree at one of the local drunken shindigs. The owner of the cat, standing beneath the tree, pointed at the cat while exclaiming "get her down!" The local hicks interpreted this as a celebratory interjection such as right on or yee haw. The locals began shouting the conflation of the phrase; "git'rdone" to rejoice and take part in a shared excitement.

the modern use of git r done was developed in the early 90's by hard working white males who reached a point in their life where they wanted to actually accomplish something in life... instead of getting completely hammered and rebuilding transmissions, the started doing projects that really mattered - projects like fixing the mailbox, cleaning the house, possibly even taking a few loads to the dump. This sudden surge of progress made these men feel good, like they were doing something. So, they had to have a way in their simple minds to reaffirm that feeling of getting something done. Thus, "GITRDONE!" was born. This can be said before a task is completed to motivate them, or after a task is completed to celebrate. It is also used profusely during the process of completing a task for no apparent reason which is very obnoxious and ambient. Often used with a drawn out "Woooooo!" yelling before or after. GITRDONE!

an utterly, utterly stupid expression apparently coined by a comedian who goes by the name of "Larry the Cable Guy," which more or less means "do it" in Redneckese.
Larry the Cable Guy yelled "Git-R-Done" forty-seven times during his hour-long standup routine, and every time he did, thousands of inbred slackjawed redneck morons yelled it right back at him.
