spanish re-?

What does adding re to the front of a word mean? For example "la reputa madre que te parió"? Is it an intensifier?

Its a form of saying 2 or 3 times more for example

The 2x times whore of your mother who gave birth to you

Eres tonto (You're dumb) - Eres retonto (You're so dumb)

Usar re- para denotar énfasis creo que se usa más en México y países así. Por ejemplo "ese carro es relindo".
