lallysplain

The art of overly elaborating or pontificating about a topic, inundating the listener with an abundance of words and information, while actually providing only a minimal or insufficient understanding of the subject matter. This term describes the act of explaining things in an unnecessarily verbose or convoluted manner, leaving the recipient with more confusion than clarity.

While lallysplaining can make it seem like one has important information, it is often very quickly obvious that they have no idea what they are talking about.
