Copy Cat
Someone who copies another
Couch potato
A lazy person
No brainer
Very easy
Soak up the sun
Enjoy the sun and warmth
When pigs fly
Something that will never happen
It's raining cats and dogs
It's raining heavily
Piece of cake
Very easy
Break a leg
Good luck!
Under the weather
Feeling sick
Join a popular trend or activity
Kill two birds with one stone
Accomplishing two things at once
Spill the beans
To reveal a secret
Cost an arm and a leg
Very expensive
Have your head in the clouds
Not aware of what is happening around you
Have butterflies in my stomach
To be nervous
Take the bull by the horns
Be brave and face the challenge
Put all of the eggs in one basket
To rely on one thing
Foot in mouth
You say or do something that embarrasses another person
In the dark
Not informed about something
Speak of the devil
The person you were just talking about appears at that moment
Wild goose chase
A search for something impossible to find
Take with a grain of salt
Don't believe it is correct
A sight for sore eyes
You're happy to see someone
Once in a blue moon
Very rarely
Bob's your uncle
There you go!
