A Killer Clean

Listerine is an oral rinse that doesn’t just sting — it kills — only because it’s so effective at mowing down mouth germs. Instead of shying away from the fact, the brand is leaning into it with all its weight, celebrating its killer edge and dancing on the graves of all that cause bad breath.

Breath Threats

If you know someone whose breath is way out of line, DM their address and phone number to Listerine’s socials.

They’ll receive a harrowing reality check — along with some coupons — to get their serial sour breath on track. From breathy 1 a.m. phone calls to ransom notes and more, we’ll murder malodorous mouths once and for all.

The Breath Sentence

By not killing your bad breath, you risk bad breath killing the vibe. Listerine will give the smelly masses a chance to check themselves in bars and restaurants with halimeters that quantify halitosis. If your breath is relatively fresh, you’ll be rewarded a coupon for Listerine so you can keep it that way. If it’s foul, you’ll be assessed The Breath Sentence — a complimentary mini bottle of Listerine and a urgent command to use it ASAP.

Gravestone Bottles

Listerine will launch a bottle redesign in the shape and style of gravestones. That way the last image mouth germs see is one of death.

Odor-bituaries

Even though bad breath deserves to die, someone needs to get the word out. Listerine will take out obituaries in newspapers small and big to tell the story of bad breath’s pitful life and painful death.

License to Swill

99.9% of bacteria is not enough. Striving to make a stronger product, Listerine will test a new prototype formula with the ultra-powerful Everclear as the inactive alcohol ingredient.

The only way to get these bottles is by taking a mouthwash safety test on Listerine’s website. Upon completion, a permit is added to your Apple and Samsung wallet that you can show at applicable drugstores to make your purchase.

Bottles Behind Bars

Locked away for countless counts of murder of mouth germs, all of these prototype Listerine x Everclear bottles will be placed in maximum-security containment in drugstores. Only by showing a mouthwash permit will an employee surrender custody of the deadly liquid to customers.
