没意思你就适可而止
[méi yì sī nĭ jiù shì kĕ ér zhĭ]
The name means that if something doesn't interest you, then you can stop at a proper time. It reflects a casual and straightforward attitude: If someone thinks that the present interaction or event is uninteresting, they will express it directly rather than being insincere or wasting each other's time. "Shi Ke Er Zhi" means stopping just at a proper limit.
