What does the slang term "shapey" mean?

According to the urban slang dictionary, shapey is used as a word to describe something that has no stable shape but moves around a lot or transforms its shape often. Shapely is used to describe someone (usually a female) who has a nice figure, a good shape, whose body is attractive.

I am ancient. I do not know 'shapey', and it is not recognised by my spell checker.   I do know 'shapely',  referring to something or someone which looks lovely.

Not something that would be polite to discuss on here. Just look it up.
