I'm going to pig out tonight
To eat a lot (menjar molt)
It costs an arm and a leg
It's very expensive (és molt car)
This is a piece of cake
It's very easy (és molt fàcil)
Hey, hold your horses!
Stop and think about something (parar a pensar detingudament abans d'actuar o dir alguna cosa)
Let the cat out of the bag
Tell or reveal a secret (explicar o revelar un secret)
He has got ants in his pants
To be excited, nervous (estar nerviós, angoixat, inquiet..)
I'm all ears!
I'm listening to you (t'estic escoltant)
Once in a blue moon
Something infrequent (que no passa sovint)
I feel under the weather
To be ill / sad (estar malalt o trist)
I am in hot water
To be in trouble (estar en problemes)
