يعني انك تلاقي حد يشبهك وبيفكر نفس تفكيرك

I'm waiting to know the meaning for the other idioms 

Answer 2

the bottom line describes the ultimate outcome of a situation or the most important or fundamental facet of that situation. When someone asks for the bottom line, he wants to cut out all superfluous details and focus on the primary problem or objective.

ex : The bottom line is, as it’s been written and spoken in various ways throughout the course of this great country’s history, “I may not agree with what you say, but I will defend to the death your right to say it ” (The Lockport Union-Sun & Journal)

Answer 3

The bottom line is the most important fact about what you're discussing

For example : the bottom line is if you love somebody you have to accept them no matter what

On the same wavelength : to share with someone else the same interests and opinions

For example

-how does indian food

-that what i was going to suggest, we must be on the same wavelength

I have no idea about other idioms but i'm looking forward for the answers.
