Just as certain English speakers believe that a mélange is more sophisticated than a mixture, so in France sometimes using an English word will make you appear cooler or more sophisticated. They are likely to be confused and frightened if you take their use of one English word to start a lengthy technical conversation in English with them. And in bad news, you can't just toss in a random English word when you've forgotten what it is in French. Cool - yes, to sound cool, you say cool. Throwing in a casual c'est cool or il est si cool will really make you fit in with the cool crowd.
