Mary Jane is very unique and has the beauty of a goddess. She has a heart that is pure, full of integrity, and is so very caring. She is agile in so many ways and knows how to maneuver therefore she is super athletic and has a rocking body meaning she is thick! She is loyal and rides for those she loves dearly. If you lose her or break her trust you will regret it severely because she is one in a million and will always be there until you give her a reason not to be. Mary Jane is a blessing but hurting her will cause you more pain then her because she can become ruthless. Do not let her smile fool you, it has many different meaning to it.
I guess nobody ever knew this. A Mary Jane is a type of girl's shoe. It's those shoes that have the single ankle strap, and the rounded toe, and are usually black (but white ones are also common). There are also high heel versions for older women.
So you see, it isn't just Peter Parker's girlfriend, or that...other meaning. Surely some of you girls out there have worn Mary Janes at least once in your life.
