Meaning
To be intelligent enough to understand simple things.
Cultural Background
In Spain, this phrase is often accompanied by a physical gesture: placing two fingers horizontally against the forehead. While understood, Mexicans might also use 'No le sube el agua al tinaco' (The water doesn't go up to the tank) to mean the same thing. Argentines are very direct with this idiom, often using it in political debates or when discussing football (soccer) tactics. The concept of 'sentido común' is often considered more important than formal education in many rural or traditional Hispanic communities.
Careful with the target
Calling someone 'sin dos dedos de frente' is a direct insult to their intelligence. Use it about third parties or in very close friendships.
The 'Ni' Factor
Always add 'ni' (No tiene ni dos dedos...) to sound more like a native speaker when you're frustrated.
