Get a shiarrhea mug for your Uncle Vivek.
when you have explosive diarrhea poop that is too shy to come out. come on, it's diarrhea, it's meant to come out fast and furious! usually happens after a night of drinking and then spending the night in an unfamiliar place.
i got to the bathroom and i knew i had to go, but apparently it was shiarrhea. finally, once i got comfortable with my surroundings, it came out.
