Hairstyle popularized by leader of 80's pop band Kajagoogoo. Now more often associated with Wapanese due to similarity to anime character hairstyles and possibly associated with loser-mating theme of said band's hit song "Shy, Shy"
"Oh, I love your Kajagoodo. It's so Limahl."
"Don't be so gay!"
"No, you're so gay!"
"Nooo, you're gay!"
