墨殪心跳独自情杀
[mò yì xīn tiào dú zì qíng shā]
This username might be difficult to directly understand for foreigners. '墨' stands for ink which sometimes implies elegance or literariness; '殪' means dead or kill, '心跳' refers to heartbeat and '独自情杀' may indicate feeling emotionally heartbroken alone. Generally, this could represent a very poetic or metaphorical expression of one's sorrowful feelings in an almost literary manner.
