Oh!モーレツ
From the English "Panchira wiki":https://en.wikipedia.org/wiki/Panchira#Origins

"In 1969, the Japanese oil company Maruzen Sekiyuu released a television commercial featuring Rooza Ogawa in a short mini-skirt that gets blown up by the wind with her forming her lips into an 'O' in surprise. This led to children imitating her line "Oh Mouretsu" (Oh！モーレツ, too much, radical), and a fad for skaato-mekuri (スカート捲り flipping up of a girl's skirt).[11] Ogawa subsequently appeared in a TV show Oh Sore Miyo (Oh! それ見よ, literally "look at that," but actually a pun on 'O Sole Mio,' a neapolitan song 'my sunshine') that again featured scenes of her mini-skirt blowing up."
