CockBlock 

CockBlock is when your friend keeps stopping you from engaging in sexual activity, fourth time at New Year’s Eve is an example and the tag CockBlock is appropriate. Don’t be that person, go home to six dogs and go for a walk instead.

Cockblock 

The true identity of a fictional character that likes to go by the name of Asia Argento in a light novel/anime series known as Highschool DxD

“Do you want to attack me?”

Buchou spoke as if she had seen through my heart. As usual it seemed like my thoughts were easy to read.

“If Cockblock wasn't here, I may have been attacked… seems like during our time alone…”
