Using 'aff' as a mild euphemism or minced oath for a stronger curse word; making light of something through playful swearing.
From dialectal or informal British English 'aff' or 'affs,' a euphemistic alteration of profanity. The '-ing' form creates the present participle of this informal verb.
British speakers use 'affing' to curse without actually cursing—it's like saying 'frick' instead of something stronger, except 'aff' sounds more cheeky and distinctly British!
