present participle. The most joyous flagellation possible! Great for parties! Yippee and hand me a stick!
Real citation: "The first anniversary of the death of Ronald Reagan has just passed, and for some inexplicable reason, an angry mob did not descend on his Simi Valley grave, dig up his corpse, drag it from the back of a Prius, string it up legs-first from an oak tree and thrash it with golf clubs and weedeaters until nothing remained but a dusty clump of hair. Comparisons would surely have been made to the cathartic pinata-flogging of Mussolini's carcass exactly 60 years earlier, not just because the two spectacles looked so similar, but because necro-lynching Reagan would do a lot to restore the dignity of most Americans."

Made-up citation: "The sun is beaming, and the birds are tweeting. Love is in the air, and I'm giddy as a schoolgirl on crack. What a day for a picnic and pinata-flogging."
