Stun with outrageous rates (5)
I believe the answer is:
taser
'stun' is the definition.
I know nothing about this answer so I can't judge whether this works.
'outrageous rates' is the wordplay.
'outrageous' is an anagram indicator (an outrageous spelling).
'rates' anagrammed gives 'TASER'.
'with' is the link.
Can you help me to learn more?
(Other definitions for taser that I've seen before include "Stunning device" , "Electrical weapon" , "Shocking weapon" , "The weapon delivers a temporary paralysing electric shock" , "Device using electrified darts to stun" .)
