Conversation Jacker 

Almost immediately after beginning to tell a story, you are interrupted by someone who begins to tell their own story of how the same thing happened to them. The interrupter continues to talk about themselves, and they never ask you about your story as if it never happened.

"I began to tell Stephanie how I almost got into an accident today, but she started telling me how she almost got into an accident as soon as I started my story!Then she just kept talking about all the accidents she almost got into in her life and never asked me about my accident. She's such a conversation Jacker."

Noun - one who overhears your conversation and inserts their own personal thoughts into said conversation without invitation. Often the hi-jacker's words will have no relevance to your conversation and has only served to take said conversation on a 20 minute tangent to nowhere.

Verbal piracy at its apex, bringing your conversation to its nadir.

"So I was discussing the bar scene at my alma-mater with Jen when Elle hi-jacked our conversation and we ended up talking about brownies for twenty minutes. Dammit."
-"Bro she is a conversation hi-jacker, you gotta be careful."
