Put your foot down

Make no bones about it

Make out like a bandit

Make waves

Make your blood boil

Make your flesh crawl

Make your hair stand on end

Make your toes curl

Make yourself scarce

Man Friday

Man in the street

Man of his word

Man of letters

Man of means

Man of parts

Man of straw

Man of the cloth

Man on the Clapham omnibus

Man proposes, God disposes

Man upstairs

Man’s best friend

Man’s man

Many a slip twixt cup and lip

Many hands make light work

Many happy returns

Many moons ago

March to the beat of your own drum

Mark my words

Mark someone’s card

Marked man

Matter of life and death

Mealy-mouthed

Meat and drink

Meat and potatoes

Meet someone halfway
