Historical analysis of a line from Miss Suzy
Perhaps we can propose a progression for Ms Suzy, where each stage of the process is motivated (somewhat like Neogrammarian sound change analyses).
This is all hypothetical of course, because I don't have any corroborating evidence, but I think this series of changes makes some sense.
(Stage 1) "I'll cut off your / behind" (kitsuchan's version)
Where "cut" makes sense because phones get cut off, and you can (technically) cut off people's buttocks
(Stage 2) "I'll chop off your / behind" (satyreyes' version)
Loses the semantic connection with telephones, but maintains the idea of removing the butt with a blade
(Stage 3) "I'll kick you in your / behind" (possibly unattested?)
Loses the cutting idea, but reinforces the butt connect, because kicking in butts is very common (lexically and in action)
(Stage 4) "I'll kick you right / behind" (my version)
Loses the butt connection altogether, but matches the song's rhythm better than the previous stage
(Stage 5) "I will shove you in / behind" (ataralas' version)
While kicking people behind refrigerators seems to be a difficult feat, shoving people into that situation is much more realistic.
