What means for American people the expression "million box"?
I heard in a song "you make feel like a million box". I suppose that is like unique or amazing.

Question

Answer

Ah... The phrase is actually "million bucks".  A "buck" is a slang term in the United States for a dollar bill.  So, this phrase means that the gentlemen makes the lady in the song feel like a million dollars - idiomatically - he makes her feel very special.

Ciao for now!

Answer

They probably said a million bucks, bucks is a way to say money. They are trying to say you make me feel like valuable, like a million dollars. 
Hope I helped :)

Answer

Marito, creeme que es la primera vez que utilizo ese término que por cierto siempre lo he criticado porque Americanos somos todos los que nacimos y vivimos en algún país de América, es sólo que no supe cómo plantear la pregunta.
Gracias por tu intervención... pura vida!

Answer

¿Te refieres a los americanos o sólo a los que viven en estados unidos?
