Baa-ching
The sad cry of a person who spends money just because they're told to. It's like a sheep being forced to buy a cash register.
My dad bought a $1000 vacuum cleaner. Baa-ching! It’s the worst.
I had to buy a $300 watch. Baa-ching! It’s broken.
My sister spent $200 on a hat. Baa-ching! It’s pink.
