Social Miscreant

Someone who's behavior is socially vile, villainous, base or malicious which breaks the rules of common social norms. Someone who makes harmful, insulting or hurtful comments with no consideration given to the feelings of the recipient.

My co-worker said to me after I told him my aunt died: " I would hate to be in your family". He is absolutely a Social Miscreant.

This lady told my friend after she coughed to clear her throat: "Don't worry about the cough, we are all going to die anyway". A Social Miscreant on the loose.
