Cock block refers to an individual (primarly male) who constantly keeps the penis limp. In the process of trying to get a girls head down your pants or any other type of that activity; there is one other cockblock present who keeps you from getting any poon to speak of. A Cockblock would be known to never get anything but a big stick in their face.

See Luke Patola (prime cockblock-ideal example)

Carley- "Yeah sure"
Luke- "I'll follow!"
Kent- "Your a Cock Block Luke"

A move executed by a female during sex to prevent full penetration because the male's cock is too big. The move is executed in almost any sexual position, by the female bringing her arms up, putting her hands on the males waist or thighs and pushing away with her fingers, resulting in the cock reversing its penetration and also preventing any further full thrusts by the male to achieve maximum depth.
