Fliff 

Slang term for money, especially money cast about in a casual manner, such as when buying rounds of drinks for people you don't know or even dislike, just to make yourself feel like the life of the party.

Seems to have been invented by comic genious brad neely.

"Professor Brother was the life of the science department's big Oppenheimer piñata party. That is, until the fliff throwing came to an abrupt end."

"A true Patriarch knows how to rock out with his fliff out."

Guy1 - "You aren't into yiffing are you?"

Guy2 - "Nah man i'm into fiffing."
