Her mother apparently is not taking the jokes personally. Unphased, she studies her personal planner at another table. I imagine she is penciling in an activity for tonight: Teach Abigail the finer points of etiquette, i.e. not to tell yo’ mama jokes in public. Or perhaps: Teach Abigail more yo’ mama jokes, ones people haven’t heard before. I guess it depends on what she takes more pride in.
Wikipedia says yo’ mama insults are especially likely to incite violence. Should I be worried? I thought they were a thing of the nineties and they went out of style like Vanilla Ice and bowl cut hairstyles. I guess I was mistaken. The art of maternal insult lives on.
