See blonde squirming: why is she red in the face? (9)
I believe the answer is:
nosebleed
'why is she red in the face?' is the definition.
I can't tell whether this definition defines the answer.
'see blonde squirming' is the wordplay.
'squirming' is an anagram indicator (I've seen this in other clues).
'see'+'blonde'='seeblonde'
'seeblonde' anagrammed gives 'NOSEBLEED'.
(Other definitions for nosebleed that I've seen before include "Epistaxis" , "Outpouring from snout" , "Result of a punch on the schnozzle?" .)
