擘口（上迸陌反考聲云手裂也廣雅手分也說文撝擘也從手辟聲也）。

Tearing the mouth (擘口; the first character is pronounced with the fanqie 迸陌 [bò]; the Kaosheng says it means tearing apart by hand; the Guangya says it means dividing by hand; the Shuowen jiezi says it means to pull apart by hand; it takes 'hand' [手] as semantic and 辟 as phonetic).
