Now, I’d say the really correct usage would be “a bit of a faff” but if you find saying that too much faff it’s all the same to me mate.
Anyway, I’m on the drag getting to the shops. I need to fix a picture thas on the huh. ;)
A good example of 'faff' is when you join a queue, get to the teller and they tell you a) you needed to take a number and/or b) you're in the wrong line.
Oh, no. A faff is an activity, rather than a scenario. Going to the bank could be a faff, but your example is just a bloody nuisance...
