    the industry standard nowadays seems to be {master-follower}

    see the following references:

    this also makes more sense - no need to employ a morally reprehensible term for a hierachical computer/technological controls arrangement... for example, we would designate connectors as "male" and "female", not "male" and "whore".... both cases "make the point" in a somewhat descriptive sense, however it is best to make the point using non morally reprehensible or inflammatory terms

    excellent question, btw!
