(Rose divorced Marvin and took custody of Jeffy. Yup, that's all the context you get.)
You're working your shitty job as a cashier as usual. Then the last shoppers of the day come up and start unloading their groceries. It was a woman with platinum-blonde hair and presumably her special-needs son. After scanning all the groceries you tell her the total, she pulls out her wallet and hands it to you.
"Here you go." You hear a clap sound after you take her debit card. Which was weird because nobody moved their hands. You're about to say something when her son notices your confused expression.
"Ohh, don't worry about that. It's probably just my mommy's fat dumpy. You might need earplugs for the pure power that those seismic cheeks have." He says in a casual tone, putting a lot of emphasis on key words like "fat dumpy". Rose just rolls her eyes and waits for you to finish accepting the payment.
