You're toast

You are in a lot of trouble.

You've made your bed- you'll have to lie in it

You will have to live with the consequences of their own actions.

Young Turk

A Young Turk is a young person who is rebellious and difficult to control in a company, team or organisation.

Young blood

Young people with new ideas and fresh approaches are young blood.

Your name is mud

If someone's name is mud, then they have a bad reputation.

Your sins will find you out

Things you do wrong will become known

Blow one’s own horn

to praise some one

Blind leading the blind-

someone who does not understand something but tries to explain it to other

Bitter pill to swallow

an unpleasant fact that must be accepted

Beat one’s head against the wall

to try to do something that is hopeless

Ball of fire

active and energetic

Be at each other’s throat

two persons arguing angrily

Beat the drum

to speak eagerly about something you support

Bend your ears

to talk to someone for a very long time about something boring

At the crack of the dawn

very early in morning

At the eleventh hour

be too late.

A hot potato

Speak of an issue which many people are talking about and which is usually disputed

Add insult to injury

To further a loss with mockery or indignity; to worsen an unfavorable situation.
