Vivir de la sopa boba

Vivir de la sopa boba
 

Somebody lives de la sopa boba when they don't work at all, and live in the house, doing nothing, and the rest work for you.

In English the phrase is to live off someone or something.

Example: He lost his job eight months ago, and now he's living off his
girlfriend's salary.

I heard the terms "free loader" and "moocher" applied to such people. Some people are ashame of doing manual labor but are not ashame of being a free loader.

I agree with you. To freeload and to mooch off seem like good translations for vivir la sopa de boba.

To mooch (without off) is a less passive action. (He's on the corner moochin' cigarettes).

Also, plainly, "to live at somebody else's expenses".

(In Spanish also "vivir del cuento"... or "ser un chupóptero")
To be a sponger, scrounger...
