(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.
1. Any unexplained or paranormal activity that prevents a male from "getting some action."
2. Any such attempt by a ghost to engage in cockblocking of a male through weird noises, change of ambient room temperature, or "getting involved" with said action. Most likely done by ghosts who delighted in cockblocking while they were alive.
Dang, did you hear Johnny got ghost cockblocked when Gina felt a cold hand on her ass that wasn't his?
