The word 'smugger' originates from the verb 'smug' (from the dialectal English 'smugge', meaning to be pleased or self-satisfied) combined with the suffix '-er' (meaning a person who). A 'smugger' refers to a person who is excessively self-satisfied or complacent.
Think of someone who is 'self-satisfied' ('smug') and the '-er' indicates that this person embodies that quality. A smugger is someone who is overly pleased with themselves.
