Deal with it is a meme that is used most often as a response to a disapproval. The image or GIF associated with this meme usually involves the subject wearing sunglasses. As in this case, Godzilla wears sunglasses.
The meme “Shit just got real” came from Bad Boys 2, a 2003 action movie starring Will Smith and Martin Lawrence. This means that something has just been escalated to a whole new level, and the image macro usually involves an intense expression.
