Shot decapitated Buffalo Bill? (3)
I believe the answer is:
tab
'buffalo bill?' is the definition.
'tab' can be an answer for 'bill?' (a tab is a bill at a bar). I am unsure of the 'buffalo' bit.
'shot decapitated' is the wordplay.
'shot' becomes 'stab' (I've seen this before).
'decapitated' means to remove the first letter.
'stab' with its initial letter removed is 'TAB'.
Can you help me to learn more?
(Other definitions for tab that I've seen before include "Text indent key" , "The bill in a restaurant" , "Bar tally; small flap" , "Ring pull" , "Tag" .)
