Valve is politely recommending that Steam Deck owners avoid inhaling its exhaust fumes after some gamers posted online about secretly enjoying the smell.
It is occasionally amusing to go to Wikipedia's manual of style "words to watch" page:
This page in a nutshell: Be cautious with expressions that may introduce bias, lack precision, or include offensive terms. Use clear, direct language. Let facts alone do the talking.
Then look at some news headlines and see how many of them violate the rules on that page. Headlines are shit.
