Teeter cancel
Teeter Canceling (or TC) involves canceling any animation into a teeter animation. Any standing technique can then be used out of a teeter.
Teeter Canceling does not work in Super Smash Bros. Brawl.
Application
Animations that can be canceled with the teeter cancel include the dash and aerial attacks.
TC Dash-dance
This technique involves canceling the dash with a teeter and then starting up another dash in the opposite direction. There is no dash stop animation since the first dash is canceled.
Attack out of a dash
Any standing attack can be used out of a teeter. One common use for this property is to run to an edge into a teeter animation and then performing the attack. This technique is useful for edgeguarding.
Combos
Since this technique removes lag both from the dashing animation and from aerial attacks (especially B aerials), it can be used to continue combos.
