drop off the hooks
pass
turn up one's toes
take a dirt nap
demise
cash in
kick the bucket
expire
hand in one's checks
meet one's end
depart
pop one's clogs
keel over
cop one's whack
draw one's last breath
interment
croak
bite the biscuit
go belly-up
peg out
kick
sputter out
bite the big one
buy it
go home
pay the debt of nature
succumb
bite the dust
hand in one's dinner pail
go the way of all the earth
flatline
slip one's wind
cark it
fall off one's perch
toddle off
cross the Styx
go
cock one's toes
inhumation
revel
interfection
ktenology
gravely
devive
self-killer
