Juggling

Juggle is a term for using a combo to repeatedly hit someone in the air without letting them recover or hit the ground. The name comes from the fact that it vaguely resembles the motion that objects make when juggled.

The most common way to juggle is using continuously Up Tilts, but Up aerials can also be used, especially for air juggling. This is a good tecnique to raise the oponnent's damage meter, however as damage increases juggling becomes harder, since the oponnent starts flying farther.

Floatiness is a disadvantage. If the opponent is good at juggling (i.e. Marth, Mario, Luigi) then since it's hard to hit the ground due to slow falling speed, you are more easily juggled (i.e. Jigglypuff, Mewtwo, Lucas). However, if you have fast falling speed (i.e. Falco, Fox, Captain Falcon), then you are much less easily juggled. Medium-slow and Medium-fast fallers are also rather hard to juggle.

Some characters, like Mewtwo, have ways to escape juggles (Teleport, in its case). Air dodging is especially effective, as are momentum-changing aerials. Some characters have a Stall-Then-Fall move that can be used to counter juggling. Using a counterattack such as Marth or Ike's Counter works as well.
