长发及腰不如短发凉快久溺深海不如跳海痛快
[zhăng fā jí yāo bù rú duăn fā liáng kuài jiŭ nì shēn hăi bù rú tiào hăi tòng kuài]
This long nickname can be understood as a saying that it's cooler for one to have short hair rather than waist-length hair, also implying that being in prolonged difficult situations isn't easy, yet jumping out (like literally jumping from deep sea) may bring immediate comfort.
