So Ill 

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

It's so nice out, I think I'll leave it out 

"It's so nice out, I think I'll leave it out" is a phrase used when stating pleasant weather. The phrase implies that the weather is so nice, you'll leave your dick out, hanging brain, because the cool breeze feels so nice on one's genitalia.

Man, it's 73 degrees outside? It's so nice out, I think I'll leave it out!
