Tirarse el pisto

Tirarse el pisto
 

Does this mean to take the credit for?

I know "darse el pisto"
to emphasise oneself, to magnitude oneself

"tirarse el pisto" then means saying something important is done by me....

"mira, ayer ganó en la bolsa y se está dando/tirando el pisto, a pesar de que se arriesgó mucho..."

saludos :D

Typical in Madrid , place where I come from.

Por Ejemplo "Tirate el pisto e invítate a unas cervezas"
"¿ No me dejas 5 euros ? ¡Anda y tírate el pisto ! "

Means " be cool" in the sense of being generous like " be a good buddy" or " behave good with me"

Nothing to do with "Pisto" alone , which is a typical Spanish food made of tomatoes , peppers and spices.
