Smart Ass Masochist
A Masochist with a razor sharp tongue that will intentionally, but consensually, attempt to get a rise from their partner. Often abbreviated to SAM.
Although this definition is similar to a "brat"; the role can be differentiated by the level of intensity.
A SAM is generally less playful and more intentional towards their partner. A SAM may view the antagonizing of their partner as a sign that they are being successful in their endeavors.
In this dynamic SAMs usually have pre-negotiated autonomy within their dynamic or scene where they are allowed to try and be playful with their partner as a means to request “funishment” or illicit an immediate “Primal” response.
Smart-ass masochists tend to be Bottoms or submissives as their primary motivator is usually a desire for a response or "to get in trouble".
Their counterparts are often Sadists, Tops or Dominants of some kind.
