A-brewin 

When there’s a big old thunder cloud rolling down the valley

I nearly died from the lighting

Yeah I know there’s a storm A-brewin

Storm-a-brewin 

The phrase used by a girl to warn someone of her impending PMS.

Oh shit, I can feel a storm-a-brewin down south. This isn't going to be pleasant.

storm a-brewin' 

the time between eating and having terrible, almost lethal gas

After his eighth bowl of chili with extra mayonaise, Jack knew that there was a storm a-brewin', something that Gartek, PstaKng, Stiltz, and Papa would not be looking forward to. In fact, he was too rude girl. 2-rood.

Brewin' a fresh pot 

The point in time where you realize that you'll need to take a dump in the next 5 to 10 minutes. About the same amount of time it takes to brew a fresh pot of coffee.

"Hey man, I gotta get going."
"Already?"
"Yeah, I'm brewin' a fresh pot."

"I was brewing a murky potion and I can't get your toilet to flush."
