Someone who farts int he bath tube and bites at the bubbles, laughing there ass off.
Jessie was not that bright and the highlight of her day was farting in the tub and biting at the bubbles. That stupid little bubble biter would laugh so hard the whole neighborhood could here her over the car alarms. "Whoohoowee, I snorklips", she would say. We loved her and later she even learned to change her own diapers.
