Here's a quote from the author of The Freshmen, Brian Vander Ark:
"STOP A BABY'S BREATH, AND A SHOE FULL OF RICE, NO. first of all, forget the NO. stop a baby's breath is just that. abort the baby. a shoe full of rice is a result of a wedding. so--stop a baby's breath AND then you stop a wedding. she's pregnant, get her to abort, and then there's no wedding."
Q: Hey, does anyone know what does "a shoe full of rice" means?
A: It's just supposed to symbolize a wedding; at some weddings, they throw rice.
