Untidy person getting right into scrape (6)
I believe the answer is:
scruff
'untidy person' is the definition.
(I've seen this before)
'right into scrape' is the wordplay.
'right' becomes 'r' (common abbreviation).
'into' is an insertion indicator.
'scrape' becomes 'scuff' (scuffing is a kind of scraping).
'r' going into 'scuff' is 'SCRUFF'.
'getting' is the link.
(Other definitions for scruff that I've seen before include "One hardly washing" , "Back of a cat's neck" , "Unkempt individual" , "Untidy person - nape of neck" , "Back of the neck of, say, cat" .)
