'in a hurry' is the definition.
(I've seen this before)

'hates going haywire' is the wordplay.
'hates' can be anagrammed to 'HASTE'.

(Other definitions for haste that I've seen before include "Heats (anag.)" , "Excessive speed or urgency" , "More of this proverbially slows you down" , "Inconsiderate speed" , "Hurriedness" .)
