There are plenty of words to describe the kids in the video, see Moron, see also addle-pate, ass, blockhead, bonehead, boob, cretin, dimwit, dingbat, dolt, dope, dork, dumbbell, dumbo, dummy, dunce, dunderhead, fool, goose, halfwit, idiot, ignoramus, imbecile, lamebrain, loony, loser, lunkhead, mental defective, muttonhead, nerd, numskull, simp, simpleton, stoop, stupid, tomfool
but to insinuate a racial slur suggesting that the color of ones skin has something to do with ones intelligence is uncalled for.
