Kimoi Girls (キモーイガールズ) is a futaba channel meme based on a panel (post #326017) from the short comic "PAY BACK" by Nitta Jun, in which two nameless schoolgirls mock a virgin boy (Nakano Ryuuichi). This eromanga is a part of his 2002 book, Datsu! Doutei.
This meme was popularized by the IOSYS flash, 'Kanbu de tomatte sugu tokeru ～ Kyouki no Udongein' (post #91177).
"えーマジ童貞!?" (What, really, you're a virgin!?)
"キモーイ" (How pathetic!)
"童貞が許されるのは小学生までだよねー" (Being a virgin is totally unacceptable past grade school.)
