They're thrown from horses in rodeos (7)
I believe the answer is:
lariats
'rodeos' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for lariats that I've seen before include "Lassos" , "Long noosed ropes" , "Lasso ropes" , "Animal tethers" .)
