Futae no Kiwami

Origin

During the Kyoto arc of the anime Rurouni Kenshin, various characters fight against a power-crazed tyrant named Makoto Shishio, in an intense battle spanning several episodes.

After it transpired that the English dub arguably butchered the dialogue of the characters during this segment, people decided to poke fun at the somewhat humurous and at times unfitting voicing, and created a fad out it by exploiting the characters’ vocalisation of their fighting techniques and more memorable quotes; not least of which Sanosuke Sagara’s ‘Futae no Kiwami’ technique for which the meme is known.

With it’s development, random clips and audio of some other characters from the English, Spanish, Latin American and Portuguese dubs were included – not even the original Japanese version was spared.
The meme is also sometimes referred to as CCO or 44O (Shishio) 4 → Shi in japanese, C pronounced similar, plus the O, makes it Shishio.
