exit
close one's eyes for the last time
perish
give up the ghost
kill
fleet
go the way of all flesh
push up daisies
bereave
demise
expire
meet one's doom
pass in one's checks
keel over
hand in one's checks
drop off the hooks
cark it
bite the dust
bite the biscuit
cock one's toes
fall off one's perch
go home
kick
cash in
bite the big one
pass on
snuff it
depart
go the way of all the earth
go belly-up
go out
extinguish
meet one's end
check out
hand in one's dinner pail
cross the Styx
cash in one's chips
croak
go
pass
cop one's whack
join the choir invisible
pass away
kick the bucket
draw one's last breath
buy it
go to sleep
flatline
