他的名字我禁忌
[tā de míng zì wŏ jìn jì]
"His Name Is My Taboo" implies that someone's name is so special or hurtful to the user, it has become taboo for them to mention. The person may have complicated feelings or a significant story tied to this particular individual, suggesting there might be some untouchable secrets or emotions in the user's mind that are hard to talk about or forget.
