Yah boo sucks

Yank my chain

Yell bloody murder

Yellow press

Yellow streak

Yellow-bellied

Yen

Yeoman’s service

Yes-man

Yesterday’s man or Yesterday’s woman

Yesterday’s news

You are what you eat

You can catch more flies with honey than with vinegar

You can choose your friends, but you can’t choose your family

You can lead a horse to water, but you can’t make it drink

You can say that again

You can’t beat that with a stick

You can’t fight City Hall

You can’t get there from here

You can’t have cake and the topping, too

You can’t have your cake and eat it

You can’t hide elephants in mouseholes

You can’t make a silk purse out of a sow’s ear

You can’t make an omelette without breaking eggs

You can’t take it with you

You can’t teach an old dog new tricks

You can’t unring a bell

You could cut it with a knife

You could have knocked me down with a feather

You do not get a dog and bark yourself

You get what you pay for

You pays your money and you takes your chances

You pays your money and you takes your choice

You reap what you sow

You said it!

You scratch my back and I’ll scratch yours

You what?

You’re toast

You’ve got rocks in your head

You’ve made your bed- you’ll have to lie in it

Young blood

Young Turk

Your belly button is bigger than your stomach

Your call

Your name is mud

Your sins will find you out
