Broomrape is an act of sexual assault with a broom handle, usually followed by the brush, depending on the slackness of the victim. Originally used as a sadomasochistic act of foreplay, it is now more commonly used as a way of describing an convincing victory.
"I just destroyed some guy on counter-striker. I seriously broomraped that guy."
"I can't believe the broomraping I just got."
