in-two-ruptor
A person who, in what is no doubt an effort to look as knowledgeable as another in a given conversation, gives up listening and tries with their allotted conversational brainpower to predict the last two (sometimes one when they are feeling lax) words of your sentence. once predicted, they will try to time themselves saying it on top of you doing so, allegedly establishing their knowledge on whatever you're talking about.
