a meep is a fart that is borderline diarreah. it usually smells almost deadly and can cause a number of harsh side effects (i.e. eye watering, nostril burning, gagging, and even vomiting in some rare cases.) it smells almost immediately and the smell lingers for a long time. if you are in the car and someone meeps you will definitely need to open the windows. the smell may be described as "thick," "pungent," or "gnarly."
