走路太骚会摔跤得瑟过劲必闪腰
[zŏu lù tài sāo huì shuāi jiāo dé sè guò jìng bì shăn yāo]
A humorous remark warning not to over-exaggerate (both literally in body language when walking and metaphorically). Being too showy can result in falling (tripping) and straining yourself (hurting your back), symbolizing overdoing any actions leading to negative consequences.
