While looking into this question asking for a word for someone who tries to impress another, I kept thinking of something I heard in the video game Dishonored:
Blow off, choffer!
It is used as a randomized reaction by the NPCs. I've always interpreted 'choffer' to be synonymous to 'boaster', but this was apparently only based on the usage in the game, since I cannot find a suitable meaning for it (online, at least).
Merriam-Webster gives as its definition:
a portable heater or chafing dish
Then there is the similar sounding (and indubitably related) word 'chauffer':
a small, portable stove.
Wiktionary also suggests an etymology related to both 'chauffer' and 'chauffeur', but they don't seem to really fit the dialogue.
I can imagine how someone who is full of hot air is referred to as a stove, since hot air carries the meaning "empty, exaggerated, or pretentious talk or writing", but AFAIK the word 'chauffer' is too obscure to have that association come about freely.
Urban Dictionary has a more fitting definition, but this could actually have been influenced by the game itself: "a general term meaning a person who is a dick, a douchebag, a jerk, or someone who has done something stupid."
The most logical explanation was found on Reddit, a user mentioning it could be a made-up word to establish a cultural distinction for increased immersion (perhaps inspired by the word 'taffer' as an alternative for 'thief' in the video game of that name).
But then I came upon someone on the Steam forums comparing it to "yarn choffer", which apparently is "Old English slang for someone who tells "tall tales"". I can't find that definition elsewhere.
Can someone clue me in on the etymology and/or meaning of the word "choffer"?
