You kids sure like your wacky water bottle challenges, huh? Oh, and you definitely love the completely-useless-except-sometimes-if-you're-really-really-good-at-soccer rabona kicks. Well this eight-year-old happens to be very good at both of those things, so we thought we'd leave it for you here.So go ahead: marvel in his prowess, be simultaneously awestruck and ashamed at your own incompetence in comparison. Such is the lethal blow dealt by the rabona water bottle challenge and the eight-year-old administering it. It has killed you. It's good.
