tink
querk
bite the dust
bite the big one
join the choir invisible
cross the Styx
pay the debt of nature
buy it
meet one's doom
kick the bucket
pop one's clogs
gut
demise
expire
cash in
quell
suck the kumara
drop off the hooks
cock one's toes
depart
hand in one's dinner pail
peg it
peg out
keel over
take a dirt nap
toddle off
croak
turn up one's toes
cark it
flatline
go out
meet one's end
pass
fall off one's perch
go to sleep
go
go home
draw one's last breath
turn to dust
pass away
sputter out
pass in one's checks
pass the river
go the way of all the earth
hand in one's checks
pass on
succumb
cash in one's chips
go belly-up
