What does cS mean?

[Aisu64]

At first I thought it was crouch but I noticed a player notating a combo something like:[...] cS > 2S [...]

I've read countless threads and no one says what it means, and its not mentioned in the notations wiki.

Close slash.  Slash universally has two different forms, one when you're close and one when you're not, which essentially makes them completely different normals.  For example Bedman's c.S is a vertical hitting buzzsaw slam thing, while his f.S is the buzzsaws being stabbed outwards at the opponent.  As this is only true for stand slash attacks, you won't see this with the crouch or air versions.

Thanks this clears up a whole lot
