That's totally DotNose of her, I mean it's right there in black and white.
When something is very apparent and written all over someones face, yet the person is not aware of the situation (only others around them), they are being a "dotnose".

When someone is being a "dotnose", one can inform them by saying "you have a dot on your nose".
Is one of the most offensive words in the English language, more so than cunt, and black people find the word more offensive than nigger.

"When i walked in to the room, it was clear that it was a dotnose situation, and so i quickly left."
