From the manufacturers of Pearl Harbor, I bring you...an ode to statutory rape:
Really, guys? "Under 18"? This is kind of creepy. (Being the color of drying blood doesn't help. Was she beaten and left for dead before Chris Hansen got there?) Also, it doesn't seem designed to increase sales. People under eighteen are perpetually obsessed with being able to pass for over twenty-one, so they can sneak into bars and get drinks, and I don't think people over eighteen have a burning desire to be confused with jailbait.
But maybe I'm being uncharitable. Under 18 could refer to lots of other things:
--The amount of days this nail polish will remain on sale before they yank it from the shelves.
--How attractive this color is on a scale from 1 to 100.
--The number of satisfied purchasers.
--The IQ of the person who brainstormed this name.
