The act of quickly and sloppily shoving your change along with your receipt into your wallet after making a purchase.
I was trying to look cool for the hot cashier by putting my nonchalantly throwing change and receipt into my wallet after buying some dranks at the gas station, but it turned into a Stash N Mash and the cashier just laughed at me.
