Frenchman's cry as Bruce Lee almost stumbles (5,4)
I believe the answer is:
sacre bleu
'frenchman's cry' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'as bruce lee almost stumbles' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'stumbles' is an anagram indicator (I've seen 'stumbling' mean this).
'as'+'bruce'+'lee'='asbrucelee'
'asbrucelee' with its last letter removed is 'asbrucele'.
'asbrucele' with letters rearranged gives 'SACRE BLEU'.
Can you help me to learn more?
(Other definitions for sacre bleu that I've seen before include "Nice exclamation" , "holy cow at Lourdes" , "in Calais, an indication of exasperation" .)
