mortal coil

Alluding to Hamlet.^[1] The two senses result from two interpretations of the word coil, one taking it to mean “tumult, confusion, fuss”, the other “case, wrapping”. In either case, the phrase “shuffle off this mortal coil” must mean “die”. Since "shuffle off" is generally taken to mean "get rid of" or "evade" it is likely that in the sense that Shakespeare used it, it was specifically referring to the act of suicide.

He then leaves his shuffled-off “mortal coil” hanging upon a fragment of dirty cobweb, as before described.

     Shakespeare represents the human body under various figures: a coil: a case: a frame: a machine: a vesture: a heft: a motion or puppet: &c. It has been contended that in Hamlet’s speech, the ‘mortal coil’ is the coil, i.e. trouble of turmoil, incident to man’s mortal state: but the analogies are too strong in favor of the ‘mortal coil’ being what Fletcher calls the ‘case of flesh’ (Bonduca, iv. 1).
