Also known as: マン的, 女の子に急所攻撃
Kicking or Hitting a female character in the genitals or crotch.
Contrary to popular belief among males, it is indeed quite painful for a woman to get kicked down there, mainly due to all the nerve endings that are concentrated in that area.
It can be a form of erotic play described as Cunt Busting or Ryona.
