Something that is very easy
A piece of cake
To do something too soon
To jump the gun
To really like sweet things
To have a sweet tooth
A search for something that is impossible to find
Wild goose chase
Very sad and depressed
Down in the dumps
Someone who is very mentally and physically strong
Tough cookie
Something you don't really like is...
not my cup of tea
To accidentally reveal a secret
To let the cat out of the bag
Someone who is very quick to understand and react to things is...
On the ball
When you feel very excited and nervous about something, you have...
Butterflies in your stomach
To allow someone to escape from a difficult situation
To let someone off the hook
To suddenly start doing an activity that has become very popular
To jump on the bandwagon
When something makes you really annoyed and angry, it...
drives you up the wall
