The lightning-fast dinner eating completed by a mother that has limited time before a child will need assistance. It is particularly noteworthy when the youngest child is 10 years of age or older and there is no need to complete a plateful of food before her eating companions have placed napkins in their laps. The mom's plate is full of food one minute and completely eviscerated the next.
Son: "Why is Mom already clearing her plate when I just poured my first glass of milk?"
Dad: "Tsumommi!!!"
Dad: "Tsumommi!!!"

A mother's fierce verbal anger caused by the disrespect of her children, usually in the form of back-talk, eye rolling, or ignoring. It results in the stunned disbursement of every person within earshot of the event, and leaves the mother alone at the epicenter.
When Billy spoke back to his mother again that morning, it was the last straw, unleashing a tsumommy that sent all family members silently rushing throughout the house to prepare for their guests' arrival.
