Como dizer "Mente não muito brilhante" em inglês

It is how the American magazine called the pupils of USP. Jocks is a slang that means the pupils like playing sports, they have good skills of communication and they are opposite of ''nerd''.
Jocks is "dumbass athletes who get all the chicks in high school'' (atletas burros que ficam com todas as garotas no ensino médio) http://www.estadao.com.br/noticias/vida ... 0562,0.htm

Is it true ??
Kisses and Hugs,
