The last option is the closest one. There are flat MS bonuses and % MS bonuses in LoL (ok, and also multiplicative, but sssh). The rule of thumb is that cookies stack additively inside those groups and multiplicatively outside. Hence your won't stack with, but it will multiply his base MS, boot bonus (except for % part if you are weird enough to take ) and any other source of flat MS.
