1. In Walt Disney's biography I have read that he was a : "News Butcher". What does a news butcher do?
2. In Hungarian, there is a mocking word for broken-toothed, used especially by children to ridicule their peers (especially when the front teeth are broken or missing). Do you have it in English, too?
I've read some of The Animated Man, and I think that as the reference by his brother Roy was to Walt's early life, it was not to suggest he did anything untoward, like cut up news stories or change them or spin them. I think it means simply that he sold newspapers? I hope someone else can clarify that.
And polite English-speaking children would never ridicule their peers. (I'm kidding!) But I don't know of any corresponding phrase. If we were to call someone "toothless" it might suggest they were very old, not just losing their baby teeth.
