Gruntus 

Nickname for a large VERY heavily muscled man, more likely a powerlifter or strongman than a bodybuilder. Usually used when the guy looks the part-- sweat-soaked T-shirt, lifting belt, chalk dust, etc. Calling a woman strength athlete "Gruntus" is usually an insult, so choose wisely.

GymRat: "I'm gonna do some deadlifts, got any chalk?"
Lifter: "Naah, go ask Gruntus over at the power rack."
GymRat: "No way, man, he looks like he'd snap me like a toothpick!"

Gruntosaurus Rex 

taking a dinosaur-sized crap; would win the "shit of the year" contest; the kind of dump where you lose weight.

After not crapping for a week, I sat down and loaded up the bowl with a Gruntosaurus Rex.

Runny grunts 

Runny shit, diarrhea, watery poop.

Goddddd, I was taking a shit dude and it was sooo watery and runny and I was grunting really loud as the watery poo came flying out my asshole.

So this afternoon I went to the bathroom. I had to shit so bad that I couldnt hold it prior. The second I pulled my pants down runny grunts went flying all over the back of the toilet seat. It was nasty!
