jerks are just mean-spirited and crude.

bullies deliberately target those they view as weaker, usually out of spite or a sense of inferiority.

a jerk will generally do crude and mean-spirited things but they don't really care who they are doing it to.. they are generally rude to everyone.

bullies reserve their thuggish behavior to an individual or group they feel won't easily fight back.
