Obfusticate
When your guts go on a full-blown meltdown and your lower half is doing multiple things at once, like pooping, peeing, and maybe even bleeding.
My dog had a full-on obfusticate during the car ride to the vet.
She had a menstrual cycle and diarrhea during the big test.
He pooped, peed, and farted all at once during the group presentation.
