The Poopking poopism was invented in 17 September, 2012 when the YTPMV 'Usual Poopking' came out. It slowly raised in popularity, peaking in 2013, when many YTPMVs were being made using it. After that, it declined.
Poopking is today seen as simply a fas that struck in YTPMV.
The poopism starts by using an action screen, usually flashing, then with a circle with a character standing on it.
