bonergrab
When someone grabs a mans boner, usually when there naked and squeezing it as hard as they can making this male in loads of pain.
My girlfriend and I were walking down the street and she notices that I have a boner. She then pulls down my shorts and my underwear exposing my boner and then gives me the worst bonergrab I have ever gotten. I then fall to the ground in loads of pain. Then she lifts me up and knees me in the balls continuously. I then fall to the ground and I land flat on my balls, crushing them which hurt even more. Everyone was watching and it was so embarrassing and painful.
