It's the friction associated with either a fluid against itself or something moving across or thru the fluid.
This could be a gas or liquid; both are fluids.
This friction could be something moving thru the fluid; as in a boat, submarine, a bird or plane, etc., or it could be the fluid moving against something. Air blowing across land, mountains, or a river/creek flowing.
Does this help?

It's a force opposing the motion of an object, as a result of the object traveling through a fluid.
Gases and liquids are both classified as fluids (a fluid is anything that can "flow"); so fluid friction applies to things that are traveling through gases (like the air), or through liquids.
The term can also apply to the friction of a fluid against itself, or the friction of a fluid against the walls of a container, as the fluid tries to move.

Fluid friction is the friction between a solid object as it moves through a liquid or a gas. The drag of air on an airplane or of water on a swimmer are two examples of fluid friction.

The fluid friction is in general terms called "viscosity".It is the internal force which act b/w layers of fluid in contact and it tends to oppose the motion b/w these layers of fluid.For example if you throw a stone down an engine oil,the stone appears to descend slowly,but when the stone is thrown down water it goes down faster.Now in the first example, the engine oil has a greater viscosity than the water.

it is better to say "viscosity"
when tow layer of fluide goes through one another both of them experience some force .This force is called viscosity
