look up any word, like eiffel tower:
An individual who has crossed certain social boundaries, i.e. "the line". Typically this individual is a "habitual line stepper", or one who fails to recognize standard social norms and mores dictating proper behavior in public and in matters of social interaction.
Rick James is THE habitual line stepper. A man should never slap another man. And if he does, he should be looking to get his ass kicked.
