Equivalent of "teri lal" a Hindi phrase which means "you are right" said sarcastically (but not actually meant) [closed]

There is a saying in Hindi in India "teri lal" which translates "yours is red" which means "Whatever the case may be you are right" as in "you are always right". It is a sarcastic way of telling (usually) a know-it-all person (but not meant truly) "you are right".

Is there an equivalent version of this phrase in English?

Example

Rohan (the know-it-all): The moon is a sphere
John: hmmm
Rohan: The moon has its own light.
John: OK "teri lal" (you are right – sarcastically)

Solution 1:

Though I agree with the others that the sarcasm is usually implied in the tone of the speaker, there is an idiomatic expression which implies a non-committal agreement without sounding overly offensive: whatever you say

TFD(idioms):

whatever you say

I accept what you say, and I'm not going to argue with you.
Usually implies that one doesn't really agree with the other person, but is going to do it to avoid a conflict.

A: "Don't worry about the auditors, just run the numbers like I told you." B: "OK, whatever you say, boss."

A: "I told you, my parents let me borrow the car whenever I want." B: "Whatever you say."

Solution 2:

The most direct parallel might be the English expression "Yeah, right."

On the surface, it literally means, Yes, you are correct, but is universally accepted as meaning just the opposite, e.g., "No way," or "As if."
