1. n. Someone who doesn't do anything at all with their life. Some people procrastinate, a michi doesn't even procrastinate, he employs his/her time to do absolutely nothing. There are reported cases of michies sitting in a closet to avoid even seeing.
2. v. To cease any and all activity. Proceed with caution when miching, for there are known cases of severe atrophy of muscles after extended periods of time miching, and even death.
Example 1: Doctor: Your situation is very serious. You cannot do absolutely any work, efforts, or stress. I would recommend you to take a michi clinic where you learn how to avoid everything and lead an extremely boring life.
Example 2: If you're swimming and you spot a shark, stand still, or better yet, try to michi as well as you can without drowning!
