The first two characters, 临时 (línshí), form a common word meaning “temporary” or “at the time when something is about to happen.” The last three, 抱佛脚 (bào fó jiǎo), mean “to hug the Buddha's feet.” Combined, they create the literal picture: “Just before the critical moment, to hug the Buddha's feet.” This vividly illustrates the figurative meaning of seeking salvation or a solution at the very last second.
