Hasshaku-sama, "the eight-foot lady," is a creature first told on Japan’s 2ch forum in 2008, described as a woman roughly eight cheok (about 2.4 meters) tall. She is said to make a low "po, po, po" sound and to bewitch children by calling their names.
What matters is that she was born not in oral tradition but on an internet forum. With each retelling details are added and altered as she spreads — a specimen of modern lore in which the record itself makes the entity grow.
