含笑半步癫七步丧命散
[hán xiào bàn bù diān qī bù sāng mìng sàn]
This complicated username comes from a combination of different sources. The first phrase '含笑半步癫' can refer to an old traditional martial arts technique that causes one's target to act like they're intoxicated without realizing they’re under attack. Meanwhile '七步丧命散' refers to a lethal poison which leaves no time for redemption; only allowing a person to move 7 steps before it takes effect. The name could imply danger but also wit.
