be a dead mosquita
The Spanish expression 'ser una mosquita muerta' translates literally to 'to be a dead mosquito' in English. However, it is used idiomatically to describe someone who appears innocent or harmless but is actually cunning or deceitful. This phrase often refers to individuals who may seem mild-mannered on the surface but possess hidden motives or are capable of manipulative behavior. It highlights the contrast between outward appearances and true intentions.
