When someone who tries to intimidate another person, they will flinch quickly towards that person, and exercise a quick widening of the eyes, in effort to scare away the supposed moron who tried to intimidate them in the first place. Usually, the kid who gives the dagger eyes is much more adapted to survive through mockery, and this action helps to scare off possible douche bags who try to scare the dagger eyed kid.
"Hey man did you see what Mike just did to me?"

"Nah what happened?"

"Dude he just gave me the dagger eyes, I was so scared, i think i pooped a little!"

"Dude, you better not mess with that bad ass anymore, he's dangerous!"
