have one foot in the grave
have had it
kick
pay the debt of nature
depart
fall off one's perch
kick the bucket
turn to dust
pop one's clogs
peg out
draw one's last breath
sputter out
buy it
pass away
bite the biscuit
cock one's toes
drop off the hooks
go belly-up
cop one's whack
go the way of all the earth
meet one's end
turn up one's toes
succumb
bite the dust
go to sleep
go home
pass
hand in one's checks
keel over
pass the river
peg it
querk
suck the kumara
toddle off
go out
cross the Styx
flatline
take a dirt nap
slip one's wind
join the choir invisible
cash in
pass in one's checks
demise
cark it
croak
pass on
bite the big one
cash in one's chips
hand in one's dinner pail
