A kind of 4koma meme which includes two images of four IGN staff members. One image shows the men in a stoic gaze while the other sees them in a jovial mood after being titillated by an unknown image. Some images may not show the original guys but other people or characters parodying their positions.
According to Peer Schneider, the guy at the far right, the two images show their respective genuine reactions to keynote speeches given by Miyamoto Shigeru at E3 2003 and 2004 about Nintendo's then upcoming offerings.
The name of the meme comes from the fact that the IGN staffers depicted are American, and thus gaijin (foreigners) from the Japanese perspective.
