Jammer is a gootraxian that loves music. They will try to convince someone to put the headphones on and listen to the song that is playing at the moment. if they refuse to put the headphones on, jammer will say.. “come on! They’re playing a great song!” Or something like that. If you put the headphones on, you will be addicted to music after the first song ends. If you keep refusing, jammer will grab you and you will start to turn into a jammer. its very easy to resist the music, humans are weak
