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