(I'm guessing this is some British slang for being in jail or dead?)
From the lyrics of Mika's "Dr. John":
I look for joy in a strange place
From the back of the bar
From afar I see the look on my mama's face
When her son's in the corner, undone
She says that my life is over
"Boy, you don't know what you got till it's gone
Come put your head upon my shoulder"
She gave me her hand, but I ignored her
