to be sick as a dog
to be seiously ill
a road hog
a driver whose car goes all over the road
hit the roof
get angry
a monkey business
silly or foolish things happening
to be in a pickle
to be in trouble, have problems
to pay an arm and a leg
pay a lot of money
Bring home the bacon
earn money
Hit the hay
go to sleep
Up in the air
something that hasn't been done yet
Kill two birds with one stone
to be able to do two thing at once
Piece of cake
something very easy
Break a leg
wishing good luck
Put all eggs in one basket
to depend for your success on a single person or plan of action
to fall head over heels for
to be completely in love with smb
to tie the knot
to get married
puppy love
the first romantic love that a young person feels for someone else
