American's a jerk (4)
I believe the answer is:
yank
I believe this is a double definition.
'american's' is the first definition.
(Yank is an example)
'a jerk' is the second definition.
(thesaurus)
(Other definitions for yank that I've seen before include "Jerk, pull suddenly" , "sudden 24D [DRAW] ?" , "Sharp tug" , "Unceremoniously drag" , "American from the North" .)
