When one defecates and the excrement from his/her buttox comes out like shrapnel from a pinapple grenade.

A high velocity, airborne, ejection of brown matter that is difficult or impossible to avoid. The result is soiled clothing and/or impregnated skin (particularly the face).
Fuck it... I was strimming the long grass in the back yard and the dogs have laid some hidden piles of crap that I did not see. I have hit a steaming pile and I have been hit by the resulting Shit Shrapnel. It is all over my t-shirt and my face looks like I have a thousand brown freckles. It fucking stinks and I think I may have got some in my mouth...
