It's a unit of mass. Pound is technically a unit of force, though for everyday use we treat it as if it was a unit of mass. Sometimes we used lbf and lbm to distinguish the two, but IIRC slug is the fundamental unit of mass in the Imperial system. Honestly, haven't had to deal with it in 30 years so it's all a bit fuzzy.
