A guy/girl, especialy friend or family who intentionately or not stops you from getting laid...it can be done by phone, visiting, etc.
I was about to lose my virginity, when a Maniac friend of mine called to ask if i was watching T.V. Because of that cockblocker I missed my chance...

Cock blocking is not always a bad thing. Sometimes it is necessary to keep a friend from getting ass that he wouldn't normally go for, but he is to fucked up to know better.
Ben was so fucked up that he was trying to get with a fat ugly bitch, so we cock blocked him to keep him out of the nasty.
