Idioms Game

[Mohamed]

Peace be upon you

Today I want to start a new game: idioms game.
I will start by giving you an idiom and you must find its meaning, explain it in a good way, and give us a new one.
Please let's avoid "thanks" and "you're welcome".. Let's learn new expressions together, do researches, improve our style..
God bless you
Let's start
