低内存头脑仅存七秒记忆
[dī nèi cún tóu năo jĭn cún qī miăo jì yì]
Refers to having only a 7-second memory as if the brain is running low on memory space, akin to goldfish which popular belief mistakenly claims can only remember things for seven seconds. This nickname reflects a self-deprecating acknowledgment of one's forgetful nature.
