I'm not partically fond of it and we also started doing a warm up in drama class containing that name, so it's even worse imo.
Just for the sake of it, this is the exercise:
When we say
Mo- we crouch down with our arms stretched out as if holding a giant ball and say it in a deep voice.
The -ni- part is squealed as high as you can on tiptoes and your arms stretched far up.
And the -ca part is said in a normal voice slowly going back into a normal upright position.
Do that over and over again and you'll see why it doesn't work imo.
Saying that, it's not the worst name, I'd prever it over quite a lot of names anytime, just not for me!
