Koopa Hopping
From SmashWiki, the Super Smash Bros. wiki
Koopa Hopping is a technique found in SSBB wherein Bowser can jump without actually touching the ground. To Koopa Hop, one must use Bowser's Flying Slam in the air, then push the jump button right before touching the ground. Doing so will allow you to jump as many times as you like without the delay of landing. You can continuously perform aerial attacks and somewhat increase your mobility, among other benefits.
Luigi can perform a similar technique when using the Luigi Cyclone.
Some other names for the technique have been:
"Klaw Canceling" by KevinM on Smash World Forums.
"Claw Hopping" by Kagato on the Brawl Central forum.
"Gimpyfishing" named after the professional Bowser mainer Gimpyfish.
"The Turtle Hurdle" by StealthKiller and Phate of the Smash World Forums.
