Oy vey. Sounds like Harrasment.
Harassment
Unsolicited words or conduct which tend to annoy, alarm or abuse another person. An excellent alternate definition can be found in Canadian human rights legislation as: "a course of vexatious comment or conduct that is known or ought reasonably to be known to be unwelcome." Name-calling ("stupid", "retard" or "dummy") is a common form of harassment. (See also sexual harassment.)

And if you don't like that Canadian definition
harassment
(either harris-meant or huh-rass-meant) n. the act of systematic and/or continued unwanted and annoying actions of one party or a group, including threats and demands. The purposes may vary, including racial prejudice, personal malice, an attempt to force someone to quit a job or grant sexual favors, apply illegal pressure to collect a bill or merely gain sadistic pleasure from making someone anxious or fearful. Such activities may be the basis for a lawsuit if due to discrimination based on race or sex, a violation on the statutory limitations on collection agencies, involve revenge by an ex-spouse, or be shown to be a form of blackmail ("I'll stop bothering you if you'll go to bed with me"). The victim may file a petition for a "stay away" (restraining) order, intended to prevent contact by the offensive party. A systematic pattern of harassment by an employee against another worker may subject the employer to a lawsuit for failure to protect the worker.
