Something that is extremely strange, awkward and generally makes no sense at all. Something totally without logic and severely disjointed in all possible ways.
Origins point to a facebook wall-to-wall that reads like this:
Guy1:Man we haven't partied since the summer. But dang I just remembered I can't party this weekend either. -_-
Guy2:it was vanilla pudding!
I managed to successfully make a round square in the laboratory today using conventional house hold items.
That a lot of vanilla pudding you just uttered.
