1. James and Ryan were having a conversation about girls in their class and Sally came and totally talkblocked them forcing them to change the conversation and continue elsewhere.

2. Chris and Peter were chilling in their room talking about whether or not they would get baked but Peter's mom burst open the door leaving them to talk about other matters. She was a huge talkblock!

one step worse than a cock block. When a person interferes with other people getting acquainted. Talk blocks do not allow themselves to be elevated to the status of a cock block by ruining any chances before you even get to drop your name, leaving you shut down without the remote possibility of a sexual encounter, now or ever.
I got talk blocked by the fat bitch in the spandex.

occurs when one is trying to catch up with a friend and discuss dirt, but said friend's significant other enters the room and conversation must shift to "appropriate" topic so as not to upset the significant other or lead to unwanted interrogation. Significant other has "talk blocked" your conversation. Talk Blocker may also be any third party who walks into a conversation that the original parties do not want to share info with.
