What are blue and white stripes?

Blue and white stripes refer to the fatness of blue and white stripes (underwear).

The blue and white stripes come from the animation "Girl with a Light Voice". Qiu Shanling accidentally exposed the blue and white stripes to the audience at the Qiuying Girls' High School Garden Party. The cartoon was covered with a bowl with blue and white stripes, so the blue and white stripes became popular on the Internet.

Chuji is a transliteration of パンツ in Japanese, which means underwear. This statement is usually used by ACGN enthusiasts, and is often seen in domestic ACGN forums or barrage websites such as Acfun and bilibili. In fact, パンツ in Japanese is a foreign word introduced by Japan, which pursued westernization during the Meiji Restoration, in order to keep pace with the times. It sounds very similar to pants in English, and many countries also pronounce underwear as fat.
