Facebook users who obsessively become fans of all kinds of ridiculous pages just for the sake of it, regularly appearing in the highlights column for their latest fan-up.
A load of Facebook fannies have again misunderstood the real reason for fanning up to a page -- to actually receive wanted updates.
Fanny, fannying or fannies - to mess around like a moron - more than likely to "dither" around, as in: make a lot of fuss and look like you're doing something but acheiving diddly-squat
"Oi, stop fannying about and get those bricks up that ladder now dickhead"
"Listen you bunch of fannies - I need this doing now"
That which is unpleasant, or a mess. So called for the mentalimage of a collection of fannies, perhaps belonging to the elderly or lose of morals.
Also applied to that which shapes badly.
Stan: I'm sorry Ollie, I just can't get it right.
Ollie: Jesus wept man, you shape like a bag of fannies.
