scrilla

Bay Area slang amongst many other terms for money of variously obscure allusions. Likely a blend, the constituents of which can be seen in the same area’s scratch (“money”) + bills, the -a being from its frequency in other words for money including moola, mazuma, and mozzarella. Also possibly from the Italian-American slang usage of scarola, meaning “endive” or “lettuce” in Italian but also “money” or “dollar bill” in Italian-American slang. In a similar way, possibly derives from Spanish escarola.
