A tool who will do anything for attention. They try to invade the lives of passersby and other non-interested parties who are trying to live their own lives. Extremely insecure, the attention whore didn't get enough attention from their mommy while growing up. They try to compensate for the lack by forcing their presence onto others because they are too dimwitted to find a healthier way to cope or mature. Probably illiterate.
I wish I could tell that attention whore Harley/Rice rocket rider/biker that he should go cry to his mommy instead of rev his engine at top noise level 20 feet from my lunch table.
