無常 is the state of being “not permanent,” “not enduring,” transitory, or evolving.

It can also mean variable or changeable. In some contexts, it can refer to a ghost that is supposed to take a soul upon death. Following that, this term can also mean to pass away or die.

In the Buddhist context, this is a reminder that everything in this world is ever-changing, and all circumstances of your life are temporary.
If you take the Buddhist philosophy further, none of these circumstances are real, and your existence is an illusion. Thus, the idea of the eternal soul is perhaps just your attachment to your ego. Once you release your attachment to all impermanent things, you will be on your way to enlightenment and Buddhahood.

Language notes for this word when used outside the context of Buddhism:
In Korean Hanja, this means uncertainty, transiency, mutability, or evanescent.
In Japanese, the definition orbits closer to the state of being uncertain.

别人屁臭自家香 literally translates as:
Other people's flatulence stinks, [but] one's own is fragrant.

Figuratively, this means:
Some people criticize defects in others that they (seem to) treasure in themselves.
