a person that is useless, troublesome or annoying, a fool.

From the english dialect "Git" or "Get" meaning "Gate". When using foundry sand to cast iron objects the access point for the metal, that is the funnel shape that lets the molten iron into the sand-mould was called the gate. This gate was of no use and would have to be removed and the cast item carefully finished to remove any blemishes caused by the gate. Thus the term "Useless gate(git)" was coined.

Means idiot or rotter. Often used affectionately like bugger (noun), but when used seriously is probably more potent (but less rude) than the worst swear words.

Possibly derived from 17th century English 'get' meaning bastard.
