counterproductive advertisement 

Any advertisement that causes the viewer to boycott the product rather than purchase it. They usually cause people to cringe with disgust when they see them. This does NOT include the Snuggie and the Shamwow T.V. ads(and a few select others) because they were so over the top, which made people want to buy them as a joke.

Snorgtees, The General Insurance, That new evil Cheeto's Cheetah, Mr. Mucus Mucinex, That one fungus commercial with the animated green blob living under your toenail, various internet spam popups, Head On, and many more depending on viewer opinion.

Person: "I can't stand that guy's voice who does the Carls Jr. commercials with all the messy burgers. He makes me want to eat at Jack-in-the-Box."
Nathan44294: "That is a counterproductive advertisement."
