glinnerfication
When a middle-aged man is divorced by his wife for being an awful person and his children want nothing to do with him anymore, so naturally he turns into a terminally online twitter bigot spreading disinformation and inciting hatred against LGBTQIA+ people. Prominent examples include Graham Linehan and Elon Musk.
The glinnerfication of Elon Musk would be very funny if he weren't in a position of power.
