Let's indulge on your scenario for a minute, that you aimed to achieve mass adoption starting from small business that will (arguably) accept a token with such obscene name, and you managed to convince some to adapt. And then what? You're sure that because some emo shop in small town accept PUBE as a payment method, amazon and other big companies will then close their eyes on the name, turn their back on their company policies of safe content, defying the worldwide norm of manner, and integrate your project into their payment method?
Like I said, that would be subjective. Here's a very good example, that Prasaga project you are desperately trying to promote in your signature. I bet you're hoping that the more you bash other projects, the more people will notice your signature and will immediately jump right into it. How's that going for you? Any success so far?
Do you think the name Prasaga already guarantees a 100% bright future just because it sounds wholesome? Do you believe the name Prasaga alone is already destined for great things because it doesn't sound obscene? Do you really think people and businesses will surely adopt it because of its 'decent' name? Nah, you're completely mistaken and obviously sounds like a noob. Tell you what, boring names are easily forgotten, especially if it sounds like an Indian cow dung. If we're both talking face to face and you tell me about your project. Chances are, I'll probably ask you "what's it called again, was it Namaste? And I'm kinda confused about what's it trying to achieve because it's not connected to the name."
Unlike PubeCoin, the name is so catchy it's easily carved into memory. I bet ever since you heard the name, its starts popping on your mind out of nowhere like a last song syndrome. Even in your sleep, your brain screams PubeCoin! PubeCoin! PubeCoin! Hence, the first thing you do upon logging in is check the PubeCoin thread. See? Even if the name sounds childish/outrageous, the brand is memorable and leaves a 'lasting' impression. The name alone already explains what it is trying to promote or achieve, and that's just one of our many advantage.
