Rouge

Rouge is a term meaning "reddish", most often heard in American English referring to womens' makeup.
Illiterate science fiction fans will often describe things as "rouge" because of their complete lack of knowledge on how to correctly spell the word "rogue".
Howevar, it is in poor form to point this out because it will crack their thin layer of protection against their own sexual insecurity if you point out that "X-Wing Rouge Squadron" makes you imagine Wedge Antilles wearing womens' makeup. They just can't function as human beings due to their fascination with that erotic scenario.
