There are two kinds of cockblocks, both of which inhibit male-female intimate relations…
1. The Sudden Cockblock. You’re talking to a girl at whatever shithole you like going to, and things are actually going well. She lets out a chuckle at your lame jokes and asks personal questions, all while including a gentle arm touch to stress some amazingly intellectual point she is trying to make. You can tell she is interested, but then out of nowhere her fat, ugly friend grabs her arm and takes her away. This scenario used to produce much anger in me, but then I noticed that some girls would tell their friend to back off for a few minutes so numbers can be exchanged. If a girl really likes you, she will not let her friend execute the cockblock (unless her friend is the alpha female bitch who controls everyone). Stay focused on the girl and accept the cockblock as a normal part of female psychology: twisted hyper-jealously coated with gooey slime that automatically corrupts all future generations.
2. The Continuous Cockblock. This cockblock is more subtle but just as deadly. You are talking to a girl but get constantly interrupted by her friends, who disturb the flow and natural progression of the pick-up. The cockblockers infect your seduction with a virus that inhibits your ability to escalate the encounter into something more meaningful, like casual sex. You don’t have many options when this occurs, but you can casually allude to the “competition” you are facing and see if she gets the hint to shut out her friends for you, the random club guy. Again, if she really likes you, she will.
A higher level of zen-like awareness when it comes to cockblocking is asking yourself why you even go to places where the cockblock regularly occurs… I have yet to hear a guy whine about a grocery store produce aisle cockblock.
