pay the debt of nature
Tod
suck the kumara
expire
fall off one's perch
go to sleep
drop off the hooks
hand in one's dinner pail
flatline
hand in one's checks
quell
buy it
cop one's whack
querk
succumb
keel over
go out
kick the bucket
pass
cock one's toes
bite the biscuit
join the choir invisible
pass away
go belly-up
cash in
pass on
peg out
bite the big one
obituary
croak
pop one's clogs
meet one's doom
bite the dust
pass in one's checks
cross the Styx
depart
check out
go home
meet one's end
go the way of all the earth
sputter out
draw one's last breath
kick
cark it
peg it
slip one's wind
