While going through the slides of my course on Machine Learning, I came to the following notation:
$$E_(x,y)sim P(y-hatomega_0-hatomega_1x)^2$$
What does this notation mean? So far I have only come across notation like
$$E_f(x) g(x).$$ This notation is completely new to me. Can somebody please explain me this?

I suggest to learn to use Latex, it is really easy.

This probably means that the joint distribution of $(x, y)$ is $P$ and the expected value is taken with respect to $(x, y)$.

Yep. This appears to be true as then I can easily explain the equation that follows this notation.
