Daily grind
Daisy roots
Date rape
Day surgery
Daylight saving time
Dead ringer
Dead white European male
Designated driver
Dial down
Diamond in the rough
Dicky Dirt
Dime a dozen
Discussing Uganda
Dog and bone
Dog days of summer
Donkey's years
Don't bite the hand that feeds you
Don't count your chickens before they hatch
Don't cry over spilt milk
Don't give up the day job
Don't look a gift horse in the mouth
Don't put all your eggs in one basket
Double denim
Double header
Doubting Thomas
Down to the wire
Dressed to the nines
Drink like a fish
Drive someone up the wall
Drop in the bucket
Dropping like flies
Dry run
Duvet day
