Short for Southern Illinois or the region of the state that residents sometime refer to as Little Eygpt. It is a play on So Cal (Southern California) or NoKY (Northern Kentucky) but is particularly amusing for those from Little Eygpt, or So Ill, as, in urban dictionary terms, there is littl 'Ill' about Southern Illinois
