Boastfully

My high-school brown-haired friend Kevin boastfully adored everything about his English heritage, from the Rolls Royce to the Royal Family. He sometimes wore a black top hat for fun. One day, my gang with Kevin discussed the intrusion of Latin into the English language. He gleefully cited the word "fix" as a true Anglo-Saxon word, which I negated, indicating that it really derived from the Latin "fīgere." He knew that as a Filipino, I had also Roman ancestors. Kevin was like redheaded Michael in Grade 5, my first elementary grade on Lulu Island. He too was keen on Anglophilia.

Nixon boastfully called the seven days he spent on the Chinese mainland "the week that changed the world"–without, however, specifying whether the change was for the better or for the worse. The way he humbled himself before Mao Tse-tung and Chou En-lai reminded me of the tribute-bearing foreign emissaries of the previous centuries who went to Peking to pay homage at the Chinese Imperial Court. Nixon's hosts must have laughed in their sleeves at his behavior during their meetings.

Figures from both groups – rightwing activist Charlie Kirk and the Department of Homeland Security (DHS) – boastfully shared these images on X, with the latter sarcastically thanking South Park for helping them in their recruiting efforts. (The show responded on X by asking DHS “Wait, so we ARE relevant? #eatabagofdicks”.)
