to the last
until Kingdom come
death
last
curtains
whilst
have had it
to death
in extremis
knock on heaven's door
till
passing
through
perimortem
one's race is run
deathwards
up till
while
up until
take the biscuit
until the last dog is hung
have the biscuit
up to
flatline
suck the kumara
meet one's doom
go to sleep
go out
fall off one's perch
demise
hand in one's dinner pail
meet one's end
with one's last breath
eat it
draw one's last breath
go the way of all the earth
bite the big one
pass on
kick
have one foot in the grave
cash in one's chips
depart
drop off the hooks
predecease
go
pass the river
slip one's wind
take a dirt nap
redie
quell
