If you search for the word “posterized” in up-to-date online dictionaries, this is what you find: “A slang term depicting a play in basketball. In said play, a player dunks the ball over top or in front of another player, making a play so picturesque that it may appear on a poster, hence the term, posterized.”

Clearly, this is linked to another term frequently used in the nasty verbal wars that are common on social-media sites, with Twitter — dominated by liberal and conservative voices in elite zip codes — being the best example.

That term is “dunking.”

“Dunking” is relevant to the main topic discussed in this week’s “Crossroads” podcast (click here to tune that in) about media coverage of the death of religious broadcaster Marcus Lamb, who died of COVID-19 after using his Daystar Television Network to criticize vaccine mandates and other anti-pandemic rules and guidelines, while advocating alternative treatments.

“Dunking” is defined, sort of, in this Slate article: “ ‘Dunking’ Is Delicious Sport — But it might be making Twitter even more terrible.” Here is a relevant passage:

Since Twitter rolled out the feature a couple of years ago, the quote-tweet has evolved into something like a pair of magic high-tops dispensed to every user on the service: Anyone can botch a tweet, and anyone can leap over him or her to score a couple of points—or a couple thousand likes and retweets.

The basketball term is apt: In a Twitter dunking, someone has made his point or said her piece, and instead of responding to it with a direct reply, perhaps in the spirit of equal-footed debate, the dunker seizes it like an alley-oop on his or her way to the basket. Maybe another player gets the unwitting assist, but the point is yours to be liked and retweeted not just as a reply but as a worthier tweet in its own right.

What does this look like in practice? Consider this example from the blitz of tweets about Lamb’s death. This dunk comes from the creator of the “America’s Best Christian” brand:
