A person who is not only efficient, but a professional at picking up women. It is also a play on words of the prolific batman villain "The Riddler" as his actions are efficient and well thought through like the person described.
A Vigilante/Anti-Hero with so much rizz, ego and confidence that all their victims immediately fold at the sight of them.
Most of the time its an accident, some use it to their advantage tho.
"Dude, have you heard of the Vigilantegoing around? They say their victims fold the second they see their face."
"Damn, they should call them the Rizzalante."
