This phrase is not actually slang, but a proverb. It translates to 'the blame is so ugly that nobody wants to carry it.' It is used to express the situation where nobody wants to take responsibility for a mistake or problem due to its negative consequences.
Examples
- Spanish: El proyecto falló y todos se echan la culpa. Como dice el dicho, la culpa es tan fea que nadie quiere cargar con ella.
- English: The project failed and everyone is blaming each other. As the saying goes, the blame is so ugly that nobody wants to carry it.
