Snappy as a game of cricket? (5)
I believe the answer is:
testy
This clue is a double definition.
'snappy' is the first definition.
(both can mean irritable or cranky)
'as a game of cricket?' is the second definition.
(whimsically, like a test match)
(Other definitions for testy that I've seen before include "Showing irritation" , "Ratty" , "Short-tempered" , "Irritably impatient" , "Easily annoyed" .)
