Got cockblocked by mom last night. Amy said she was ready to go all the way, but she went home instead and I got grounded. I might be a virgin for another week yet.

Someone who blocks you online and then cowardly addresses a reply post that you can’t see or reply to
Hey, I can only assume you can’t see Jim’s reply to you on my timeline cause you didn’t reply to that weak ass shit with another bitch slap. He’s such a cockblocker. So predictable...

Originally meaning when a person is about to engage in sexual activity and a person (family member, friend, child etc.) stops any chance of doing so. This can also be applied to any day to day non-sexual activity. Such as going out with friends, smoking bud, etc.
"Dude, I was guna get some ass, but then her best friend, who I think is a dyke and totally has a crush on her, cockblocked me."
"Fuck man, we were going to the movies, but then my mom cockblocked me."
