George Nagaoka

George Nagaoka (ジョルジュ長岡, Joruju Nagaoka) is a very simple AA character who swings his left arm and chants about breasts, hoping it'd encourage women to show their breasts. He was, most likely, created and named on 2channel's /news4vip/ board around August 5, 2004.¹⁾

Alternate chants

( ﾟ∀ﾟ)o彡゜ Eirin! Eirin! (えーりん！えーりん！)
In the Touhou Project song, “Flight of the Bamboo Cutter ~ Lunatic Princess”, some people imagined that the 1:21 mark sounded like Kaguya calling for Eirin's help. This was further popularized by the 2004 arrange, "Help me, ERINNNNNN!!", by BeatMario under the “COOL&CREATE” doujin circle.
- ( ﾟ∀ﾟ)o彡゜ Chāhan! Chāhan! (チャーハン！チャーハン！)
  For the Gachimuchi-themed MAD video of said arrange, the chant became 'chāhan' (fried rice),²⁾ which is actually a mishearing of Billy Herrington's “How do you like that, huh?” line.
- ( ﾟ∀ﾟ)o彡゜ AMEN† AMEN†
  There was a lesser known Hellsing-themed MAD video of said arrange, where the chant became Alexander Andersen's utterance of Amen from the OVA.³⁾
( ﾟ∀ﾟ)o彡゜ Fuu♪ Fuu♪ (ﾌｳｩｯ♪ﾌｳｩｯ♪)
Some versions of the comedic “DanJo” song⁴⁾ adds the arm pump and 'foo' sounds at the 0:47 mark.⁵⁾
( ﾟ∀ﾟ)o彡゜ Kobe! Kobe! (神戸！神戸！)
In the Marines–BayStars exhibition match on March 3, 2010, some musicians decided to borrow the Touhou Project song, “U.N. Owen Was Her?”, as a stadium anthem and chant for Takumi Kobe.⁶⁾ Marines won 4–0, and it turns out that they'd also win the 2010 Japan Series that season.
( ﾟ∀ﾟ)o彡゜ Gēchisu! Gēchisu! (ゲーチス！ゲーチス！)
In the fifth generation of Pokémon games, Ghetsis' theme notably has a backing chant of his name.

Notes

In the CIA's Vault 7 leak from 2017, their list of Japanese-style emoticons notably contains the Touhou Project variant, 'Eirin! Eirin!',⁷⁾ rather than the general 'Oppai! Oppai!' variant.
