你说早已麻木了双腿之间
[nĭ shuō zăo yĭ má mù le shuāng tuĭ zhī jiān]
The net name implies that after going through certain life experiences or events (which may involve some degree of intimacy or physical contact related to the lower body area) a state of indifference or lack of sensation has been reached. Overall, it seems a bit sad and cynical about love or sexual relations.
