Where do git-git originated?

Answer 1

In the Potteries, the area around Stoke on Trent, England, though this may be an earlier word taken over from metalworkers. When one makes an article by the process of casting - whether in bronze, silver, gold, iron or clay slip - there has to be a short tunnel from the mould to the outside, through which to pour in the metal or slip. When the finished article is removed from the mould, there is attached to it a short strip which is a casting of the tunnel. This bit, which is useless, to be broken off and thrown away, is the GIT. Hence the expression, 'you useless git'.
