It's exclaimed, most often in a group, when playing a videogame and the screen suddenly starts to flash with vibrant colors or in black and white. An example would be in MegaMan 2 at Wily's Castle, every time you destoy a boss, the black background starts to flash vividly and quickly in black and white. It's seen more if the game is played in a dark room, in which the whole room is lit up.

Get the SEIZUREmug. 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, "About 5 minutes."
Player 2, "Oh yeah! I see what you mean. Wow! That is weird."
Player 1, "Seizure!!!!!"
Player 2, "How long has it been going for?"
Player 1, "About 5 minutes."
Player 2, "Oh yeah! I see what you mean. Wow! That is weird."
Player 1, "Seizure!!!!!"
