Yes, I think it is a misnomer. At least in reference to one wing dropping. As others have said, if both wings stall evenly, there is no wing drop, regardless of where the stall originates on the wing panel. Technically, the actual tip NEVER stalls, under any condition. The lift goes to zero at the tip and it has a lift slope of 0 (infinite angle of attack capability). BUT, you can have the middle portion of the wing stalling before the root and in that case, the entire wing panel reaches stall almost simultaneously. If there's even 1 degree difference between left and right wing panels, autorotation sets in and over she goes!
