Nodversation 

A one-sided conversation in which one party wishes the other to smile and nod, but not to bother contributing anything more substantial than the occasion "uh huh" or "really." The speaking party might as well be conversing with a pole or trash bin, but likes the reassurance of the presence of a breathing organism Similar to a nonversation, it is a conversation that is not really going anywhere.

"That girl is so self-absorbed. Every time I see her, she tries to pull me into a nodversation, during which I am bombarded with the mundane drama of her not-so-interesting dating life."
