look up any word, like hipster:
 
1.
An influential and judgmental moped gang from Chicago, IL
Rando 1: "Peddy Cash never comes to my stupid Thursday night rides."

Grom 1: "I love riding mopeds but Peddy Cash hates me."

Hater Dude: "What, do you have to be Peddy Cash to get into this place?"

Grom 2: "I threw a kit on it but Peddy Cash didnt care."

2.
An assumed motive for why teenagers dress like skanks.
To earn yourself some Peddy Cash.

Peddy Cash is a combination of the terms;
Pedophile and Petty Cash
1. "That skank we just drove past looks like she's in for some Peddy Cash".

2."Tegan! Get yo' ass out there, and earn some Peddy Cash!"
*Aaron comically suggests a way for Tegan to pay for the Take-Away.*

3.Samantha tends to dress in a way that 12yo's shouldn't dress, thus it can be assumed that she MUST be saving for the latest Pokemon game.
