Buying Midanka is Thai, which means I have no money. Because it is frequently used by members of the Korean women's group BLACKPINK in the group variety BLACKPINKHOUSE, it has become a stalk. In addition, Lisa's fans also regard "buying rice as a card" as a code word for fans to recognize each other.

In the group variety BLACKPINKHOUSE, before four members went to the Thai market, Lisa taught three others some Thai, one of which was to buy Midanka. Later, because others basically only remembered this sentence, it became a stalk.

Thai, also known as Dai, is the language of Thai people and belongs to Sino-Tibetan language family. About 68 million people around the world use Thai. Thai is mainly used by Dai and Thai people in Thailand, Laos, Myanmar, northwestern Vietnam, northwestern Cambodia, southwestern China and northeastern India.

Thai is an analytical isolated language, and its basic vocabulary is mostly monosyllabic words. Different tones can distinguish vocabulary and grammar. Synthesis and overlapping are widely used in word formation. Like many other languages in the world, Thai is a complex and diverse mixture.
