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