Kill vampire? I look like one! (6)
I believe the answer is:
impale
'kill' is the definition.
(impaling is a kind of killing)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for impale that I've seen before include "Pierce through as with sharp stick" , "Pierce with a sharp stake" , "Pierce with a stick (as Vlad did?)" , "Pierce, me pail (anag.)" , "spit!" .)
