I'm sure most people don't have their mind in a gutter and will take interest. Besides they can snigger and still take interest.Do you want the person sitting opposite to take an interest in the device or do you want them sniggering behind their hand because you're advertising "DP" in large lit up letters? Keep in mind that unless they already know it's meant to stand for Dragonbox Pyra, (and very few will) their mind will fill in whatever words come to mind first.
