Knife Job
A knife job is when a girl takes a lot of knifes or swords and literally tares her pussy apart. Also some guys will do this to a lot of girls and turn them into a hoe floor.
Tim was giving Calysta a knife job yesterday. Damn her pussy is torn apart.

Self-explanatory idiom.
When I got spurned by Cheryl, it hurt like giving a knife a hand job.
