I just watched The Bucket List and a very good if emotional film it is.
I can understand “Shuffling off” and “Turning your toes up” along with a few more expressions but I got to wondering where the following came/originated from:
Kick the Bucket
Peg out
Pop your clogs
Croak
Doubtless there are others, the meanings of which are somewhat obscure
Pass away
Pass on
Left us
Departed
Snuff it
Bite the Big Cookie
Buy the farm
The first 5 are self explanatory, the last 2 not so
Bought the farm = going away to another place far away and not coming back?
Signing off? Lights out?
Thought of another; The Big Sleep.
Variants of ones already mentioned:
Bite it
Kick it
Buy it
Pass
Others
Meet one’s maker
Become worm food
My personal favorite for inanimate objects like servers or water heaters: went/gone “tits-up”
I’ve heard the explanation of “bought the farm” elsewhere on the Dope, but can’t remember the details…
But I did look up the snopes entry for it in time to edit. 
He’s not dead, he’s resting!
he’s circling the drain
bit the big one
10-7 (local cop code for out of service)
he was DRT (dead right there)
taking a dirt nap
assume room temperature
went belly-up
Shuffled off the mortal coil
joined the choir invisible
has ceased to be
You made that up didn’t you?
‘Bite the big cookie’ is a version of ‘bite the big one’. Perhaps from ‘bite the dust’?
‘Buy the farm’. The most common explanation I’ve heard comes from WWII, when pilots (also aircrews and soldiers) would say that when the war is over they’ll buy a farm and live a peaceful life. If someone ‘buys the farm’, then the war is over for him.
Another obvious one: Dirt nap/sleep.
My friends and I used it in high school. I did find this:
I think one or two of my friends had a mother in nursing.
No, it referes to the last plot of ground you’ll ever settle.
Hop the twig.

(j/k)
When I worked in a hospital with 7 floors, a person “went to Level 8”.
Sickest one…" they gave me 60" or “they left the building and didn’t give me 60”…£60 is the payment a doctor gets for filling out a cremation form, so either the patient died and got cremated, or they died and got buried (in which case the doctor gets nothing).
Isn’t “peg out” a cribbage term for ending the game?
Expire
Toes up in the marble orchard
irishgirl - Why do they need a special doctor-signed form for cremation. Surely dead is dead?
StG
He could only be mostly dead.
