At Doors, one of the participants mixed up his words while presenting, and said instead of ‘possibility’ the wonderful, fantastic:

“Possidifficulty”

This word has already found much usage, in my work-life particularly, for example:

“that phase of the project is an area of possidifficulty”

Or, with elbow-patches on my blazer and attempting my best, most-pompous Carl-Sagan-type voice:

“Social software is an area that presents boundless possidifficulties”

Try it yourself! The possidifficulties are endless!
