"Mango" (singular) is used to describe a person who is astonishingly good looking and as desirable as a ripe, sweet tropical fruit.
Example:
Giovanni: Ya sé que no soy muy atractivo y tú... eres un mango. Pero quisiera que saliéramos juntos.
Belinda: ¡Mangos! Contigo, ni a la esquina.
Giovanni: I know I am not very handsome, and you are incredibly attractive. yet i would like ypu to go out with me.
Belinda: Not happening. Don't kid yourself.

Mango with chili powder is a very popular snack in Mexico.
