Heres my post from a thread Munge started on Supertopo (presumably to getter a wider field of input on the critical question
):
This actually started as a discussion between Munge and me on Mudn'Crud.
Munge, Jaybro's definition (above) is just what I was talking about (substitute butt-cheek for shoulder though). A "scootch" isn't the same thing.
Yes. Sorry for not being explicitly propositional. But that's what the point of my post was about, if I read your response rightly. Scootch is not appropriate for the move. Scum could be, mainly because Scootch/Scooch is already defined in a way that doesn't match the moves described. Are you agreeing with me, or only to the extent that Scootch is not the right word?
More specifically, if the hiney hugging the cheek does is only partial and not an entire resting cheek, then it would be a cheek-scum. There is a chance something could come off in a cheek-scum move. But a full resting ba-dunk-a-dunk, is merely sitting, and therefore cannot be considered a climbing 'move'.
The scum definition is not well defined, but oft used, and in many different ways.
