Jump cancel throw
The jump cancel throw (abbreviated JCT) is an advanced technique in Super Smash Bros. Brawl and SSB4 that allows the player to throw an item while sliding a little bit forward, similar to a glide toss. It can be performed by any character in the game. The player must have an item in their character's hand, then dash. They must then jump and cancel the dash into a throw. There are different frame limits for each character. Basically, the technique is performed by transferring the jump momentum into the toss, which is how the character slides forward.
Its applications are similar to a glide toss because the player can perform a forward, backward, forward reverse, and a backward reverse JCT. There is a slight difference between the two. Characters with a poor glide toss can use this to gain some distance.
In Ultimate, the technique is less effective due to the short hop aerial shortcut introduced, which renders it nearly impossible to perform, along with Ultimate's dash-canceling mechanics that enable players to perform regular item throws out of a dash without needing to jump-cancel first.
