goody-two-shoes
buckle down
too big for my britches
ace up my sleeve
eat my hat
knock my socks off
dressed to the nines
hanging by a thread
earned your stripes
put on your thinking cap
bee in your bonnet
shaking in your boots
very dressed up
to concentrate
impress or amaze
a person has an advantage
to act like you know everything
describes people who try to act perfect
someone is in an unsafe position
very suprised
to work hard
shown you have kills and accomplished an important task
you have been struck by an idea and are obsessed
extremely anxious or scared
