Get the Conversation Cockblock mug.
Whenever you're talking to somebody, and no matter what or how many witty or interesting things you say, they reply with things such as, "cool" or "yeah." They won't allow a good conversation by making it suck with their one word answers.
Debbie: "I was texting Conrad last night."
Sally: "What did you guys talk about?"
Debbie: "More like, "what did I talk about?" because he was being a conversational cockblock the whole time."
