Complete a task (get her done). The phrase can and is used by idiots all too often. Because it is only spoken by white trash and wanna-be white trash, the users attribute it's invention to "Larry the Cable Guy" (whoever that is) when in actuality the phrase was first made popular by John Travolta's character in the 1976 film Carrie, based on the Stephen King novel. If you're going to show what a moron you are by using this phrase, at least know when it was introduced to pop culture.
random person: I have to do some laundry.
idiot: Git Er Done!!!
random person: shut up, you're such an idiot for saying that - it's totally stupid!
