Short for Master/slave. An extreme form of D/s relationship where the slave voluntarily gives up all personal freedom to the Master or Mistress (or both).The creation of such a relationship is often marked by the giving and accepting of a collar and sometimes by the signing of pseudo-legal ownership documents.
She asked to be set free from their M/s agreement. He has said she can go as long as she finds him a new slave first.

Marks & Spencers or M&S not to be confused with S&M this is a well respected giant in the retail and catering industry serving millions of the british public daily with wonderful food and to die for St. Michael brand clothing.

This is a total piss take for clerification M&S sucks serious hobo dick there clothing would be turned down by a man wearing only pants on a typical Alaskan day and there food well......let's not go there.
"Remember when Martha told Victor to get some M&S products but he accidently got some S&M.......that was some funny shit"
