General Terms

Wiggle/Left-Right/Turnback

While running, pressing left for a short time to slow down. Useful for manipulating enemy spawns or for correcting a jump that went too far.

Long Jump

Tapping jump and immediately regrabbing and holding it to get a low jump but slow falling, resulting in a longer jump.

Clip

Falling through or getting stuck any sort of solid platform.

Wall Clip

When running into a wall at a high speed, and Mario acts as if he were standing on solid ground for a frame. Allows for a wall jump, but also kills P-Speed and spin jumps.

Corner Clip

When running into a corner at the top of a wall, and Mario hits the wall and the floor at the same time. Mario makes it to the platform, but P-Speed is lost. If Mario is going fast enough, he can actually fall through the block.

Wall Jump

Jumping on the frame(s) Mario is technically standing on solid ground during a wall clip.

Stair Clip/Slope Clip

When jumping at a shallower angle than the slope at the right place, Mario can fall through the slope.

Yoshi Clip

Using Yoshi to easily clip through a solid block. See Yoshi Clips.

Block Dupe

Abusing bad collision to create extra blocks by hitting them with an item at a particular position.

Wings

The item that Yoshi can grab to go to a bonus room and end the level prematurely. Usually refers to spawning unintended wings using block dupes. See Wings.

Shell Jump

Throwing a shell midair and jumping off of it immediately after. See Shell Jumps.

Item Swap

Allowing Yoshi to eat any sprite in the game by removing the item off of Yoshi's tongue as he is grabbing it.

Cloud

The cloud Lakitu rides around in; usually refers to the item swap that gives you a cloud in your item box. See Cloud.

Orb

The green ? orb at the end of Sunken Ghost Ship. Usually refers to the item swap that gives you an orb in your item box. See Orb.

Neutral Jump/Hopping Glitch

Abusing speed mechanics to make Mario move ever-so-slightly faster by releasing right on the D-pad. Can be used to eke out an extra game second on the clock.

Fast Yoshi

Block duping a Yoshi block, which causes Yoshi to hatch quickly. Usually used in Yoshi's Island 2 for 11 Exit runs.

Fast Fly

Abusing speed mechanics to make Mario fly faster by tapping right until Mario is flying as fast as he can. See Flying.

Pipe Fly/Door Fly

Abusing flying mechanics to retain flight after entering a door or pipe.

Cannon Fly

Getting pipe-fly through a cannon pipe in order to fly with a higher speed than normal.

Sticky Fly

Abusing flying mechanics to stick to a ceiling while flying.

Yoshi Flight

Abusing flying mechanics to enter the flying state while riding Yoshi.

One Tile Fly

Landing on a single block and taking off again.

Zips/Tornadoes/Smashola

Abusing collision mechanics to quickly move downward by pushing Mario through yellow turn blocks.

Corner Boost

Using the edge of a block to push Mario slightly forward by moving fast enough upwards. Primarily used in water levels where it can save a frame or so per corner.

P-switch Jump

When Mario lands on a p-switch, it counts as ground for 1 frame, and with a frame-perfect jump you can jump off it.

Key Jump

Mario can stand on a Key in midair, and jump off it. By pressing Y and B on the same frame, he will regrab the key while jumping, and the process can be repeated arbitrarily. Used in some difficult romhack speedruns.

Platform Boost

Moving sprite platforms will push Mario while he runs on them. As such running on platforms moving in the same direction he is moving saves time (and platforms moving the opposite direction lose time).
