How can i ask out a that i like guy?

he's in my grade very, popular, most girls like him, very sporty like me, and i and my friends thinks he likes me! Me and my friends always see him looking at me at recess so does that lead to anything? But, i have asked a guy out before but, he was like a guy i could actually talk to and he was the type of guy that says yes to every cute girl! PLEASE HELP ME!!!!
