peg it
kick the bucket

expire
pop one's clogs
peg out
succumb
depart
drop off the hooks
hand in one's checks
cash in one's chips
eat it
join the choir invisible
cark it
go home
bite the dust

suck the kumara
take a dirt nap
go belly-up
on one's deathbed
flatline
slip one's wind
sputter out
go out
kick
fall off one's perch

pass the river
turn to dust
cross the Styx
bite the big one
toddle off

go to sleep
meet one's doom
