cock block

Sometimes used by myself amongst other nerds to mean that a router or firewall is preventing a connection to a computer or server.

Friend: "Dude, I tried to log into your minecraft server but it didn't connect for some reason."

Me: "Oh, sorry my router was cock blocking you. Let me forward the right port number and try again."

cock block

The act of interfering with a friends plan to have sex.

Knowing that speedbag would be getting his going to Vegas blowjob the morning he was leaving, his good buddy thought it would be funny to cock block him and showed up at his house to pick him up 15 minutes early for the second year in a row.
