Conversation incremulate 

When someone is focusing on something else while youre telling a story and they realize youre talking, in the middle of your story they say " wait what were you saying? sorry i wasnt listening" pretty much sending the message that theyre not interested in what you have to say or theyre busy and they dont have time to talk.

Daniel: man today my teacher was talking about his mom, and then missy was like 'what about your dog?' and he was like well his name is..
Nicki: Im sorry what? i wasnt listening
Daniel: Damn, you just conversation incremulated me!
Nicki: Sorry

Conversation Thief 

An individual who comes into a conversation and (Uncleverly) lays claim to all that was said. Like they brought all the information everyone was just discussing as their own. and worse?.....Believes that it were their own. this also can border line the grotesque acts of the "Conversation Vampire"!!!

Two people are standing there talking and a third person comes into the conversation, the third person nods head and agrees and within seconds begins to repeat what was said as it was their own idea, this is a "Conversation Thief". For it is obvious from the rest of the partakers in conversation that this individual lacks his or her own opinion, ideas, etc.
