'impressive' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?

'tango? rash going topless' is the wordplay.
'tango?' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'rash' becomes 'hasty' (I've seen this before).
'going topless' means to remove the first letter.
'hasty' with its initial letter taken away is 'asty'.
't'+'asty'='TASTY'

Can you help me to learn more?
