Inattention To Detail.
I'm not sure if it's a mistranslation of an ad that originated in another country or simple incompetence, but I've been baffled by a recent Voltarol ad.
The voiceover uses the wrestling term “forearm smash” when illustrating how Voltarol has enhanced the "forehand smash" of the narrator’s wife's tennis game.
Pedantry perhaps, but it’s inexcusable given the amount of people involved in approving such a spot. People supposedly focused on engaging rather than confusing viewers.
