Dipshits come in all shapes and sizes

So I have a new coworker who seems to be a nice person and is very enthusiastic about coming to this company to be a corporate whore. On the surface, it would seem to be a great addition to the team. Work output has proven otherwise. However, this isn't where they become a dipshit. There was a five minute random discussion one day regarding cell phones and the fact that most people don't really have land lines anymore. New person says well, we have Vonage at our house and we have been really pleased with it. But, the problem is that he pronounces Vonage "vough nahzge" instead of Von ij. They don't just say it this once, but 6 times within a few sentences. I'm having a hard time making eye contact with this person when they keep repeating this word incorrectly over and over. I'm trying to figure out why they have heard the commercials for Vonage a ton of times and have heard how it is pronounced, yet feel compelled to change it to something else. As if their branding of Vonage is better than their own or something. Does it make them feel fancier to call it that? Because they are getting such inexpensive phone service, do they want to make sure you still know they can afford something much pricier?

It probably has nothing to do with anything other than it is just another dipshit in my day.
