A vengeful abusive person:
one who uses threats to manipulate
people and seeks to exact vengeance on anyone who opposes them by the most ruthless and violent means they can think of, such as kicking them in the crotch. The
abuse may be a literal kick in the crotch, or may be a metaphor for hurting the person through other means.
"I told him I was leaving him. He kicked me in the crotch with steel-toed construction
boots. Since that day, I call anyone
bent on revenge a 'crotch-kicker.'"
"The Tycoon has a history of legal intimidation. He has been involved in
3,500 lawsuits over the years. He is a lawsuit-obsessed crotch-kicker."
