No, it's not a common expression at all. I've never really heard it used in everyday language.
Definitely not. This is not something you'd hear in normal conversation. It's either something very specific to a particular situation or just a very odd made - up phrase.
I'm not entirely sure. It could be that there is no story related to someone named David that is in black and white, perhaps meaning a simple or old - fashioned kind of story.
Definitely not. It has a rather strange combination of words and concepts that are not typically put together in standard English expressions. Most people would find it confusing or even inappropriate if used without proper explanation.
No. I've not really come across this as a common expression in literature. Usually, we talk about things like 'banning' or 'censoring' a novel, but 'black out' in this context seems rather unusual.
It's not common in everyday conversation. It seems more like a slogan - like statement that those closely following Trump or his policies might use to emphasize his importance or the finality of his actions in a particular context.
No. 'End of story' is a common expression, but 'wuando' is not a known part of common English expressions. So 'wuando end of story' is not a common expression.
No, it's not really a common expression as it's self - contradictory. But it can be used creatively in certain contexts.
Sure is. People say 'a likely story' when they think what they're hearing is not very believable or seems made up. For example, if someone claims they were late because of a traffic jam that never happened, you might respond with 'A likely story!'
Prejudice is a common theme. Society often has preconceived notions about interracial relationships, which the couples in these stories have to face.
One common theme is the idea of contrast and complementarity. Just like black and white are opposites yet look great together. In a love story, the differences between the two characters, be it in appearance, personality or background, can attract them to each other and make their relationship more interesting.
