one's number is up
with one's last breath
have had it
have one foot in the grave
buy it
cock one's toes
drop off the hooks
knock on heaven's door
fall off one's perch
quell
go to sleep
pop one's clogs
toddle off
kick
turn to dust
go
go the way of all the earth
bite the dust
peg out
join the choir invisible
meet one's end
cash in one's chips
hand in one's checks
pass
hand in one's dinner pail
bite the big one
sputter out
go out
pass on
croak
slip one's wind
expire
kick the bucket
pay the debt of nature
cash in
snuff it
depart
keel over
querk
check out
cross the Styx
demise
meet one's doom
pass away
succumb
suck the kumara
flatline
take a dirt nap
pass the river
bite the biscuit
cop one's whack
go home
cark it
peg it
pass in one's checks
go belly-up
turn up one's toes
draw one's last breath
self-delete
return to dust
conk out
euth
euthanatize
help along
eat it
article of death
last gasp
extinguish
knocking on heaven's door
dying
in articulo mortis
in extremis
meet one's maker
destroy
mortally
commorient
sleep
lose one's life
close one's eyes for the last time
moribund
sudden death
self-blood
top oneself
take one's own life
an hero
end one's life
self-killing
perimortem
top
end it all
kevork
valley of death
death drive
dyingly
life-or-death
self-kill
go the way of all flesh
lose the number of one's mess
