Cotton Mouth Killer 

Cotton Mouth Killer, or CMK, is an energy drink from Norway. It has blueberry and guava flavour, and is specifically designed to kill your cotton mouth. When your thirst is dire - an ice cold can of Cotton Mouth Killer extinguishes it like an ocean hitting a fire.

Thirsty guy: "Dude. My mouth is so dry. I would pay such large amounts of money for a delicious bevarage right now."
Friend: "Have a CMK, bro. Cotton Mouth Killer will quench your thirst."

Cottonmouth Killer 

That first swig of any drink(usually an Arizona Tea product) that relieves the severe dry mouth after smoking five or six gravity bong hits. You know that feeling like your stuck in the desert without water x10.

Dude im so ripped after those gravs, but I won't be feeling euphoria until I get that cottonmouth killer from that Arizona Green Tea.
