The kind of guys who are perpetually friendzoned, show up at social events, and have no interest in talking to you, until you're vibing with a girl then they show up and immediately attempt to block the interaction.

I have zero interest in confronting them, or embarassing them. Truth be told I'd be happiest if they could just learned to talk to other guys instead of always going head-first into the friend-zoned puppy dog role.

All the same, how the fuck do you deal with white knight cockblockers without being outright confrontational?
