A j-pop group born from the money-making powerhouse that is Hello! Project (also responsible for Morning Musume), aimed primarily at pre-school to secondary-aged children that was popular from 2000 to 2004, when the group was put on "indefinite hiatus". Most of their songs were about counting, food groups, etc., with a smattering of English phrases taught by the group's one American member.
In spite of the fact that this was a group for small children, many American high school (and in some sad cases, post-high school) otaku cite Mini Moni as one of their favourite j-pop bands, because they're just so KAWAII! These people typically refuse to acknowledge that the only people over the age of five at Mini Moni concerts were parents of the children attending. It is also arguable that these people understand none of the lyrics that they so enthusiastically sing along with, as if they did, there is no way they would be calling themselves Mini Moni fans in lieu of having an IQ of 70.
Mini Moni fangirl: jankenpyon is my favorite song EVAR!
Person: You do realize that song is about playing rock, paper, scissors, right? Do you even speak Japanese?
Mini Moni fangirl: ur so baka. MINIMONIRULZ!!!
The archangel cast from heaven for leading the revolt of the angels; Satan, Lucifer, Beelzebub. Can be seen moonlighting as an alleged breakoff group from Japanese Pop idol group Morning Musume as a group of the four youngest members.
...And ye shall renounce Mini Moni from thine heart and be saved...
