If a guy constantly burps loudly around a new girlfriend, what does it mean?

That's a little weird way of saying it, but if a guy is in a new relationship, and he does it all the time, like purposely gross and not mannerly with it, does that show any signs of not liking the girl as much? I mean guys are gross I get it, but a real man would try not to be so gross about it and say excuse me after, so with him not doing that, does it point to anything? Again I don't really know how to explain it, the people who understand get it, it's not a serious question just genuinely curious on what guys think when they do that?
