Master and Slave are the names given to the "leader" device and "follower" device in the SPI data transfer protocol. While these names are operationally accurate, they do not sit well with many engineers who must use this protocol for their work. With rising social pressure, these names are likely to be changed. It would be helpful for backwards compatibility to keep the names starting with M and S for acronyms like MOSI and MISO (master out slave in; master in slave out) which is written in lots of code. Therefore the names which we suggest should be used are "Milf" and "Simp". These are words common amongst today's generation and express a similar leader-follower meaning to the out-dated terms, and they start with the same first letter. These new names would be easy to remember and provide an elegant solution to the problem at hand.
