This week's topic: Oyako Donburi.
母娘どんぶり literally translates to "mother and daughter porcelain bowl", which is a direct description of what is depicted in the comic, but the phrase is commonly used (often in the shortened form 親子丼/おやこどん oyakodon) as both the name of a chicken and egg dish commonly served in said bowls (the "mother" and "daughter" being the chicken and egg) and sexual slang for a threesome with a mother and her daughter.
