Mentally Retarded Female, as used on grossly underappreciated television show Arrested Development. Usually identified by bracelet marked with said initials. Also known as Mr. F.
Charlize Theron played Rita, a wealthy MRF from Wee Britian, who wanted to make PopPop with Michael Bluth. The mere fact that she called it that tells me that she was ready. Michael, like most other "Yanks," were unaware of her condition because it was masked by her intelligent sounding English accent.
