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