No Major Glitches (NMG), is a ruleset that requires that you beat the game without using certain restricted glitches. This is defined as follows:
Any glitch that either (a) allows Samus to move entirely into collision or (b) results in Samus's rotation suffering a lasting displacement is disallowed.
Under this ruleset, the following out-of bounds (OoB) glitches are banned:
Instances of collision updating, failing to update, or respawning do not invalidate a glitch. It is possible to die with pseudo waves and ledge warps this way, but they do not allow you to directly clip out of bounds.
You can easily check what is considered an OoB collision by seeing if it's possible for Samus to die in it.
In addition, any glitch that results in Samus's rotation suffering a lasting displacement is disallowed. This includes:
If you are unsure if a glitch is allowed, consult the Metroid Dread Speedrunning Discord server.
