欶毒（雙捉反蒼頡篇云欶歃也說文吮也從欠束聲歃音衫甲反經文從朔作朔不成字也俗用字）。

欶毒 (Pronounced with the fanqie 雙捉 [shuò]. The Cang Jie pian says: "欶 means to sip." The Shuowen says: "To suck. Analyzed as semantic 欠 and phonetic 束." 歃 is pronounced with the fanqie 衫甲 [shà]. The sūtra text writes it with 朔 as 朔, which does not constitute a character; it is a vulgar usage.)
