长腿太任性头发太麻烦
[zhăng tuĭ tài rèn xìng tóu fā tài má fán]
Long legs too willful, hair too troublesome. It's a somewhat humorous and casual saying indicating that people with certain features (like long legs) tend to act freely whereas having long hair might be a hassle, possibly implying self-mockery about one's traits.
