Tips
usage
Extremely common in spoken complaint speech. The base verb 坑 (kēng, 'pit') means 'to dig a pit for someone to fall into' → to set up / cheat. 坑爹 (kēng diē, lit. 'cheats your dad') is a popular online intensifier with the same meaning.
memory
Picture digging a literal 坑 (pit) for someone to fall into, you 坑 them. The hapless target = 人 (rén).
