great beyond
deathfulness
likam
ghoulish
morbid
flatline
fall off one's perch
check out
go
bite the dust
pass the river
peg it
bite the biscuit
snuff it
pass in one's checks
depart
go the way of all the earth
kick
meet one's doom
croak
hand in one's checks
cash in
cark it
go out
hand in one's dinner pail
join the choir invisible
pass
pop one's clogs
meet one's end
pass on
drop off the hooks
go home
cash in one's chips
pass away
cross the Styx
draw one's last breath
pay the debt of nature
buy it
cop one's whack
expire
go belly-up
go to sleep
bite the big one
kick the bucket
cock one's toes
peg out
keel over
alkylmetal
