Ricardo Milos' dance video was originally published on a gay porn site called "Jock Butt." In the video, Milos dances erotically while wearing a red bandana on his head and an American flag thong. On October 15th, 2010, the video was uploaded to NND as part of the Gachimuchi series and has since received over 500,000 views.[1] Milos' charismatic and alluring dance caught the attention of Gachimuchi fans and he soon became a recurring Gachimuchi character. Due to his similarity to the Brazilian football player Ronaldinho, NND users gave him the nickname Ro nau jii nyo (ロナウ自慰ニョ, with "自慰," or jii meaning "masturbation”). The jii pun in Milos' nickname came before Ronaldinho's nude video was leaked online.

The trigger of the Danced Like a Butterfly (蝶のように舞いーニョ, Chou No You Ni Maiinyo) fad was a video titled "Dancing like a Butterfly,” uploaded to NND on July 14th, 2011. The video got 1st rank in the NND daily video ranking and has received over 850,000 views. The video reproduced Milos’ dancing with a hand drawn animation of Yuyuko Saigyouji, a character from the Touhou series (shown below). The video featured the song "Butterfly (Upswing Mix)" by Smile.dk, known for its inclusion in the Dance Dance Revolution series.

Creators on NND began mimicking Milos' dance with hand drawn animations and 3D character models using the animation software Miku Miku Dance. Smile.dk's Butterfly was reused in many MAD videos. As of December 2018, more than 390 Danced Like a Butterfly videos have been uploaded to NND.
