It's a derivative of the "Your mom" insult. The function varies slightly from the original insult as it specifies the condition the so-called "mom" is in.

Get the your mom is a hoemug. An insult of such incredible, nonsensical idiocy that it's normally used as a barb for the beginning of a larger, meaner insult. It normally leads to Your mom's face, then Your mom, and so on and so forth.
