Grutting 

When you have sex with a fat male lorry driver from behind, but instead of actually inserting the penis into the anus, you just thrust your penis back and forth within his arse crack, using his sweaty butt cheeks to stimulate yourself.

"I'm not ready for anal just yet, would you mine if we had a go at grutting instead?" - Fat Lorry Driver

"I tottally grutted that guy at the truck stop last night, it was rough as fuck" - Guy who fucked Fat Lorry Driver

grunting a loaf 

To defecate forcefully and voluminously.

I ate a whole rotisserie chicken and seven hot dogs. Several hours later, I grunted out a massive loaf.

Grunting Face Curse 

When you're beating off to porn you are cursed to come when it cuts to a shot of the guys grunting, bright red, sweaty face.

Dude, The Grunting Face Curse struck again when I came all over the image of Ron Jeremy's face.
