D-day capacitor
A tiny brain part that only women have (mostly) that saves every stupid thing your partner does. It doesn’t tell you to say anything. It just sits there and holds all the dumb stuff until D-day, when it dumps everything on you like a pile of trash.
My D-day capacitor had enough of him forgetting my birthday 7 times.
She waited until D-day to drop the whole list of his mistakes on me like a bomb.
That capacitor was full of stupid stuff. He even spilled coffee on my laptop.
