An individual advertisement is often called an "ad" or an "advert" for convenience.
But if all #advertising is in fact #propaganda, what do we call an individual piece of propaganda? Should we call it a "prop" or a "propa"?
As in, "Aw, jeez, not another Coke prop." Or, "A propa only five minutes into the show? Fuck this."
@clew IIRC, the connotations of "prop" aren't universally positive. At least one is neutral (theater/movie props), and then there's "prop" in the sense of, "Country A continues to prop up the murderous regime of so-and-so in Country B."
