Idiot preserved meat (4)
I believe the answer is:
jerk
This could be a double definition.
'idiot' is the first definition.
(thesaurus)
'preserved meat' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
Can you help me to learn more?
(Other definitions for jerk that I've seen before include "Yank; preserve (beef)" , "kind of lift in competition" , "Quick sharp movement" , "dull person" , "contemptibly foolish person" .)
