What is The Black Widow?
1.
A sexual act where a man ejaculates on a womans hands. The women then tells the men to close his eyes. She then proceeds to throw his ejaculation like a web from her hand (taken from the Spiderman) and then hits his balls. She then runs away and leaves the man webbed and in pain.
"In return for her receiving a Spiderman from her boyfriend the night before, she gave him the Black Widow with a quickness"
