In a Fighting Game, one fighter initiates a combo by launching his opponent into the air with a strong attack, then following up with a combo or Meteor Move. This is a good strategy in many 3D fighting games, as most characters have limited air options and, in many series, can't defend when airborne. Of course, because of varying movesets among characters and series, some characters are better at it than others. When the subsequent attacks keep the character in the air, it's called a Juggle Attack or Air Combo.
