life hack(redirected from a life hack)
A simple, resourceful, and often novel action that makes one's life easier or alleviates a problem or challenge. Painting my keys with different colors of nail polish was a great life hack—it's the only way I can tell my office key from my house key! A lot of what millennials call life hacks are actually just common sense.
