MR is an acronym for "mentally retarded", which is used to communicate that a person is handicapped mentally. It is often used as a criticism for someone who says or does something dumb.
The term can be pretty controversial, which means that you should use it with discretion. Also, the acronym is rarely used so if you do come across "MR", it most likely refers to "mister." To avoid controversy, you can use the DBD or DA acronyms.
