They have used symbols which are sex related as you can see a girl with her mouth open and the wordings used such as It'll Blow. Then below they mention "Bk super seven incher" below the sandwich, we all know what it represents. This advertisement also uses Repetition as a technique as "Bk super seven incher" is repeated in the description of the meal. Are they digging into womens desires when saying "Fill your desire for something long, juicy..."
Why would they say "Fill your desire for something with a creamy sauce that will dribble down your chin" this is in a way related to sex but using food . Symbolic words are used "Wrapped for your pleasure". Another symbolism is where the sandwich is placed, it directly symbolizes a mans private area. They use a handsome guy who is well built, this could be seen as " Beautiful people". A man would want to be that guy and a lady would want that guy with her.
Looks like two hands are hiding something, very symbolic again of sex. The wordings "We're about to reveal something you'll really drool over" has a double meaning.
This advertisement by Chanel shows that to be in fashion one must leave fast food, it also implies that to be in fashion you have to be thin or slim. If you are fat you cant be in fashion.
