When a boy aged 10-12 is gay or very effeminate, and likes things that are normally only liked by teeny bopper girls of that age. Examples include guys who like Justin Bieber, boy bands, the color pink, make up, dolls, etc.
Kid 1: "Look at Craig over there with all those girls. Why do they like him so much, I think he's gay."
Kid 2: "Because he's a queeny bopper and likes all the same crap they do. He's definitely gay."
