When your games consoles: such as your xbox 1 or xbox360, your playstation 3 or playstation 4, your TV, your computer, or any other household appliance starts acting up or displaying signs of extreme malfunction. It is sometimes emphasised or exclamed by the person who's appliance is experiencing it.
Player 1, "Oh my god man! My xbox 360 controller is vibrating weirdly and I can't stop it."
Player 2, "How long has it been going for?"

Player 1, "Seizure!!!!!"
