HeadOn - Apply directly to the forehead!
HeadOn is a fad based on a commercial about a headache curing medicine called HeadOn. The fad was perhaps created despite how annoying the commercial of HeadOn was. The commercial consisted of a woman repeatedly saying "HeadOn, apply directly to the forehead!" Despite how annoying the commercial was, it came on YTMND, the first person who made a HeadOn YTMND is unknown.
