(verb) The act of thrusting your pelvis at someone and yelling "GHOST COCK!!!" in an act of surprise and humiliation. Usually used to piss someone off or catch them unaware. Originated through a gay joke that went weird somewhere, by Will, Danny and Anthony.
"GHOST COCK!!!" screamed Will as Anthony turned the corner.
"What the- Aw, fuck. How did you know I was coming?" Anthony said.
"You didn't see me, but I saw you," said Danny, laughing his ass off.
