So hungry I can eat a horse. 

starving

100

eat your words

regret what you said
100

so far so good

things are going well so far

100

get a taste of your own medicine

Get treated the way you've been treating others (negative)

100

give someone the cold shoulder

ignore someone

200

bit off more than you can chew

do more than you can handle

200

break a leg

good luch

200

to make matters worse

to make the problem worse than what it is

200

Don't cry over spilled milk 

There's no reason to complain about something that can't be fixed

200

it's raining cats and dogs

it's raining hard

300

tired as a dog

extremely sleepy

300

Call it a day

stop working on something

300

you can say that again

true, I agree

300

by the skin of your teeth

just barely

300
you live and you learn

realize you made a mistake and you've learnt from it. 

400

everything is not always peaches and cream

everything is not always as good as they seem

400
To make a long story short

keep it brief

400

your guess is as good as mine

I have know idea

400

cost and arm and a leg

very expensive

400

take a raincheck

to postpone a plan

500

bite your tongue

don't say anything

500
to pull someone's leg

to joke with someone

500

speaking of the devil

the person you are talking about just showed up.

500

break the ice

make people feel more comfortable

500

good things come to those who wait

be patient
