eat it
conk out
return to dust
croak
hand in one's dinner pail
slip one's wind
turn to dust
take a dirt nap
draw one's last breath

go home
turn up one's toes
flatline
pass on
go the way of all the earth
bite the big one
go belly-up
peg it
pass
querk
cark it
pass away
keel over
kick the bucket
expire
pass in one's checks
cash in one's chips
kick
buy it
cock one's toes
go to sleep
pop one's clogs
pay the debt of nature
cross the Styx
demise
depart
go out
bite the dust
meet one's end
quell
hand in one's checks
fall off one's perch
drop off the hooks
succumb
toddle off
join the choir invisible
suck the kumara
sputter out
check out
cash in
meet one's doom
bite the biscuit
cop one's whack
pass the river
peg out
snuff it
have one foot in the grave
push up daisies
knock on heaven's door
kill
deathward
have had it
deathwards
on the way out
lose the number of one's mess
knocking on heaven's door
help along
have had one's chips
euth
euthanatize
transition
close one's eyes for the last time
extinguish
meet one's maker
perish
