A person who personnifies a stupid cunt, a portmanteau of both words, the term is used to identify someone who personnifies a vagina of little to no intellect. In cases, 'stunt man' or 'stunt woman' may be applied to both genders interchangeably. This is actually how stunt people received the name of their profession; their overwhelming impotence and purposelessness as stupid cunts led them to this career path, because they are highly expendable.
Did you see Janet's tits during the Superbowl performance? What a brazen stunt!
