Friction can be a nuisance when it causes wear and tear -- on parts in machinery, on items of clothing, furniture, etc. Friction can also be a nuisance when it causes static electricity. The static electricity, depending on the circumstances, can cause anything from a mild shock and clothing cling to an explosion at a gas pump or near gas fumes in a building. It can also cause damage while work is being done on the insides of a computer.

In any part that you want to keep moving, like a spinning wheel, friction is just a nuisance.

A nuisance is a bothersome person or situation. In legal use, it is something that causes offense, annoyance, trouble, or injury. *In modern use, a "nuisance lawsuit" is one filed many with the hope of exacting a cash settlement in exchange for it being dropped. This is also known as "frivolous litigation."
Friction is more than a nuisance, it is a hindrance to perpetual motion. If not for friction, your car would easily get 100,000 MPG. Airplanes would glide around the world with their engines shut off. Hitting a Baseball out of the park would not be a problem. But there are problems to consider. Rain drops would not have a specific Terminal Velocity, and may be very painful when they hit you!
In several cases, friction can be a real nuisance, mainly because it wastes energy. Thus, in many engines, where there are moving parts, you'll want to decrease friction to waste less energy.

Ways that friction are beneficial: Standing - Friction allows you to stay in position instead of moving around even when you do not want to Braking of cars - Similarly, friction makes it possible to make a car stop Ways that friction is nuisance: Wear and tear - Friction produces heat, which would flatten shoe soles, smoothing the gears or other mechanics in machineries
