走个猫步给狗看
[zŏu gè māo bù jĭ gŏu kàn]
It's a humorous phrase, roughly translates to showing off walking elegantly in front of someone (usually inferior or unrefined). It implies irony when someone acts pretentiously before those whom it's nonsensical to impress. Here, 'dog' refers metaphorically to the unrefined.
