Verb. To crap on endlessly about a subject, often straying from the initial subject onto something else entirely, all the while making no sense at all, leaving your entire audience utterly confused.
"If you could stop Dounging for just a moment, you'll see that none of that makes any fucking sense at all"
"the definition of this word is, like, that word, plus like, that word, but at the same time it's like, this other thing that relates to what I was eating for breakfast the other day while watching a porno" "yeah, you know what? you really should stop dounging so much and make things a little clearer"
