How to say "to waste money" in Polish slang?

To blow up money, to spend it carelessly, freely, eg. in casinos, card games etc.
Some "rural" word would be very good... thank you!

przepuszczać forsę :) (forsa is slang for money)

Thank you! but could also you give me an example, where the verb is also slang (or have some countryside taste), not only the noun "money". I want to express the action itself with such a word.

Szastać kasą/forsą?

Przerąbać kasiorę
Przepieprzyć kasiorę (rude!)

Cinek

Szastać forsą, przepuścić kasę, przepuścić szmal (kasa, forsa, szmal = money)

Thank you very much
