Diaper Pale
1. adj. The color of a squeamish or uninitiated individual's face when he/she encounters the more objectionable contents that can sometimes be found in diapers.
I thought it was okay to change little Johnny's diaper in front of the other guests, but when Bob saw all that green baby poop his face went diaper pale and he left the room. Anyway, he'll learn to get over it if he and Jane ever decide to have a kid of their own.
