Pounds are properly force, but just as kilograms can be used as a unit of force (it annoys me, but apparently it's considered correct to use kg to mean 9.8 N), pounds get sloppily used for mass as well.
Correctly, the slug, not the pound, is the unit of mass in the fps system. It's the amount of mass which one pound of force will accelerate at one foot per second per second.
