Heck of a party (5)
I believe the answer is:
blast
'heck of a party' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for blast that I've seen before include "Severe reprimand; strong gust" , "Severely criticise" , "Blow up or swear" , "Damn - explosion" , "Sudden strong gust of wind" .)
