Put your foot in your mouth
To say something you shouldn't
By the skin of your teeth
Pulling my leg
To fool someone
Get it off your chest
to talk about something that is upsetting you
pull the wool over your eyes
to trick you
Open a hornets nest
to create some trouble
a snake in the grass
a sneaky person
a chip on your shoulder
to be angry about something in the past
Hit the nail on the head
to be correct
between a rock and a hard place
a problem with no good solutions
A green thumb
someone who can grow plans well
Sleep on it
To think about something
On cloud nine
To be very, very happy
judge a book by it's cover
to judge someone before knowing them
all thumbs
clumsy
Turn over a new leaf
to change yourself for the better
A feather in your cap
to accomplish something great
Pulling his hair out
leave no stone unturned
never giving up trying to find something
hold your tongue
stay quiet
In a pickle
having a problem that is difficult to solve
Hit the ceiling
To be very, very mad
Hit the hay
To go to bed
give the cold shoulder
to ignore someone
pull your hair out
to be very frustrated
