Pfft; Pffft. No, you're the idiot

Oh, the so many definitions of a word so...odd. Not, even a word, an expression really.
These definitions that are to follow are all the workings of www.urbandictionary.com ... so if anything sounds strange, is spelled wrong, is redundant = not my fault!
Ok, here it goes...

We'll start with the shorter:
