Flips over bystander dropping tray (5)
I believe the answer is:
bends
'flips' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bends that I've seen before include "Decompression sickness" , "Road curves" , "Diver's affliction" , "deadly to the diver" , "Buckles" .)
