When a person or vending machine gives you change from a purchase, or breaks a larger currency denomination into smaller denominations and the resulting change is unusual, inconvenient, and/or frustrating.
“I put a five in the soda machine and it gave me back 30 dimes, 7 nickels, and 55 pennies! Now I have to walk around with a fifty pound pocket of retard change!”

“I gave the pizza delivery guy a 20 and he gave me back a 5, a 2 dollar bill, a 1 with a burn hole in the middle, a peso, and a Canadian quarter. Dudes not getting a tip if he’s givin me retard change!”
