In your opinion (which is fine, we all have them). Just because you think it's terrible though, does not mean others won't like it. It wouldn't be top 100 if it wasn't loved 'in the real world' (whatever that is meant to mean). Clearly plenty of people, beyond those on mumsnet, do love it for it to be where it is in the charts.
There are many top 100 names I think are terrible too, but I accept there must be plenty of people who do love them for them to be up there in the charts.
Thank goodness we all love different names. The world would be incredibly boring if we all picked the same ones.
