Go bananas!
Act crazy or wild
pigged out
ate too much
Raining cats and dogs
It's raining very hard
Lend a hand
help
sleep like a log
sleep really well
skeletons in the closet
to have a secret
Let the cat out of the bag
told a secret
Down in the dumps
sad
When pigs fly
never
have the blues
be sad
Lend an ear
Listen
In hot water
in trouble
Hold your horses
stop or wait
Over my dead body!
I will not allow that to happen!
Get off my back!
Leave me alone!
Break a leg!
Good luck!
I have butterflies in my stomach!
I'm very nervous
Have a ball!
have fun or have a good time
Scaredy pants
scared of something
Catch a cold
get sick
Nailed it!
Did it perfectly
Break the ice
Make people feel comfortable
It's a piece of cake!
It's very easy!
