The meme originates from the youtube series: "ASDF", a series of animated movies made up of short clips made by user "TomSka". In the 6th episode, this clip features an ASDF composer "LilDeuceDeuce" lookalike jumping into a crowd, shouting "everybody do the flop" and then falling over and faceplanting the ground along with the small crowd around him. This popular clip has already created many short parodies and copies in the last month inspired by this clip.
