exit
perish
give up the ghost
bereave
go the way of all flesh
close one's eyes for the last time
kill
pass away
check out
demise
expire
turn to dust
bite the biscuit
kick the bucket
bite the big one
cark it
cock one's toes
fall off one's perch
flatline
hand in one's checks
drop off the hooks
go belly-up
kick
peg it
hand in one's dinner pail
take a dirt nap
pass the river
pop one's clogs
pay the debt of nature
meet one's doom
cross the Styx
go to sleep
pass in one's checks
suck the kumara
go home
go the way of all the earth
sputter out
cash in
disanimate
go out
toddle off
slip one's wind
quell
keel over
pass on
bite the dust
querk
turn up one's toes
go
cash in one's chips
