grumbellina 

A kind of cutesy way of telling someone they're spending too much time grousing about something. Useful for children, spouses, and anyone else you'd really like to tell to STFU, but don't want to be really mean.

OK, Grumbellina, we get it, you don't like McDonald's, you can stop talking about it now.
