look up any word, like sex:
A long drawn out sentence that says nothing, ultimately. Pretty much just talking bollocks when you're not clear on what you're saying, but trying to make it sound like you do.
"... has tremendous strength in depth."
"In comparison blah blah blah." Without comparing it to anything at all.
Another Daveism is to finishing a list that was never started. OR change tense mid-sentence.

A Daveism is the term that refers to a vocabulary mistake said by someone called Dave.

It happens quite often, especially when Dave is tired, drunk or excited.
Manda: "Quiz question one: name the title of Harper Lee's novel".

Dave: "Erm, erm, How to Kill a Mockingbird?"

Manda: "...it's just To Kill a Mockingbird. You've done a Daveism".
