look up any word, like dirty sanchez:
 
1.
Defecating and puking at the same time.
"So we go get breakfast at the diner and I am a WRECK. I have never been this nervous in my life. I can barely eat, I'm shaking, I'm freaked out. I keep watching the door. EVentually I decide I have to go to the bathroom because I've wigged myself out so badly I think I'm gonna puke and poop myself. So I pop in a stall and sit down so I can poop. Which I do. At the same time I start puking."

My friends and I call this panzershrecking, because it's blowing out of both ends.

Edit: panzerschrecking*
