i love turbulence.. as somone put it.. i love the look on passengers faces when they are all screaming like they are going to die and its a quite routine 'chop' and nothing worth worrying about.
I have had quite bad turbulence over central australia over the desert... i swear the wings were making metal grating noises. that was the only time i was kinda freaked.. because the noise was loud and we were tipping sideways. i was at the time doing tea and coffee.. the coffee pot rolled off towards the window somewhere (i was wedged in an empty row laying on the floor). i know the aircraft bends and expands and contracts.. but the noises coming from the fuselage were far worse than the extreeme roller coaster action we had going.
the kind where you have to wedge yourself under the seat bars to stop your body being lifted off the floor is kinda fun

other times i have hit the roof.. been pinned to the floor and had a cart land on top of me (or me land under the cart i cant remember)
usually turbulence if its in the galley involves crew sprawled everywhere if there are no available seats.. and lots of hysterical giggling.
i also recommend not drinking tea or hot beverages in turbulence.. tea up the nose is not good.. use a straw.
