drop dead
pop off
croak
pass
go
meet one's end
pass on
succumb
pass away
go to sleep
hand in one's checks
depart
join the choir invisible
slip one's wind
pay the debt of nature
cock one's toes
draw one's last breath
bite the biscuit
cash in one's chips
peg it
expire
sputter out
go the way of all the earth
pass in one's checks
kick
go belly-up
demise
bite the big one
take a dirt nap
toddle off
go home
cark it
flatline
fall off one's perch
peg out
turn to dust
turn up one's toes
suck the kumara
drop off the hooks
hand in one's dinner pail
meet one's doom
querk
cash in
quell
cop one's whack
keel over
check out
cross the Styx
pass the river
pop one's clogs
buy it
kick the bucket
go out
bite the dust
snuff it
fuck off
strike down
eat it
die away
conk out
return to dust
dyingly
with one's last breath
on the way out
permadie
have had it
on one's deathbed
push up daisies
have one foot in the grave
mortally
extinguish
drop like flies
in articulo mortis
instadeath
to death
in extremis
euthanatize
help along
knock on heaven's door
perish
euth
knocking on heaven's door
fatally

predecease
carry off
linger
