In Super Mario World and Super Mario Maker, holding
jump after reaching peak of the
jump arc will slow down your fall a little bit (even if you don't have cape). Regrab uses this by letting player make a smaller
jump by letting go of jump button before the peak, BUT then re-pressing the jump button later to slow down the fall - thus allowing a jump arc that isn't otherwise possible, with
short rise but
long descent. So re-pressing the button - that's the 'regrab' part.
This can also be combined with other tricks, for example there are versions of a shell jump and a pow drop with regrabs in some versions of Mario Maker.
This kaizo level has a very hard
jump. If I jump too high I hit the spikes, but if I fall too fast I will hit the grinder saw - you need a really precise regrab to just barely make it.

Hey, the Quora AI bot says that regrab is about letting go and grabbing a
vine?
-That is complete nonsense.
