Pay an arm and leg
very expensive
Bring home the bacon
earn money
hold your horses
wait
Out of the woods
Out of danger
Cold feet
becoming unsure about doing something
On the tip of my tongue
Can't think of what you were going to say
Chip in
to help with work or to help pay for something
Butter someone up
be nice to someone to get what you want
In a pickle
in trouble
Sounds fishy
sounds suspicious/not right
Hit the sack
Go to sleep
Hit the roof
to be angry
