The grommits can simply be defined by the explosive release of fecal matter. If for any reason you want to get the grommits, you can achieve this by eating scurvy food (Denny's, Perkins, any Chinese restaurant) or by taking some kind of laxative. The grommits usually consist of the liquid form of matter but sometimes consist of a log that is expelled from the rectum at a high velocity, which sometimes is referred to as a streaker.
The other day, I ate at Denny's. The omlette was very scurvy so as a result, i spent the majority of my afternoon on the commode with the grommits.

Aw, I just stepped in some dog grommit.

Gr- represents the prefix of the word "gruesome"
mit- represents the sufix of the word "vomit"
The extra "m was added for indivduality and emphasis
When the word is mentioned, it's used in the context of something that is gruesome, to the point of barfing(vommiting)
Ewwwww! Get that away from me, major grommit!
