I read each of these three examples several times and I still have no idea what you meant, outside of general displeasure. Maybe this is the point. So in a strange twist of meta your examples are way too reddit for me.

I just invented one:

"Redditsplain"

v. "To make confident, even angry assertions about facts without a strong backing, but in a literary and well-reasoned style. To make bold statements about a subject where one is still a dilettante."

This is hardly unique to Reddit, and happens on HN as well.
