批头散发办贞子
[pī tóu sàn fā bàn zhēn zi]
A creative combination where '批头散发' means to have disheveled or messy hair and '贞子' is the name of a ghost character from the Japanese horror series 'The Ring'. The username thus describes dressing messily while impersonating this frightening entity, likely intended to evoke a creepy or eccentric appearance or persona online.
