Is being annoying a form of harassment?

yes it can be, because being annoying can be done in a variety of ways. calling out names to someone constantly can get "annoying" touching someone after that person tells them not to is also annoying, if your doing something purposely to be annoying then that is harassment but if you don't have any means to annoy someone and just act yourself and its still considered annoying then that's different, its an argue- able question
