Is it correct grammar to say made you?

"Made you" is grammatically correct, but it's not a complete sentence. It's a phrase that needs more context to understand its meaning.

Here are some examples of how "made you" could be used in a sentence:

* "The movie made you cry." This is a complete sentence with the subject (movie) and verb (made) and the object (you).

* "The delicious food made you full." Again, a complete sentence with subject, verb, and object.

* "What made you laugh?" Here, "made you" is part of a question asking about the cause of someone's laughter.

In short, "made you" is grammatically correct but only as part of a larger sentence.
