For a time after the second Iraq War began on March 20, 2003, dissent against this military action was viewed as unpatriotic by many people in the United States, particularly those on the right end of the political spectrum. Arguments against the war - whatever their merit or basis - were often met by the phrase "why do you hate America"?
Now, several years later, the phrase has gained ironic usage and is more often utilized to emphasize the irrelevance, illogic, or foolishness of the original argument; see examples below.
Original usage:
Person 1: Well, I don't see why we needed to go to Iraq. Clearly Saddam Hussein was no danger to the United States.
Person 2: Why do you hate America?
Current usage:
Person 1: How can people watch professional wrestling? It's so fake.
A rhetorical question, asked in an ironic sense, derived from a supposed conservative tendency to view disagreement as unpatriotic. It is chiefly used in two situations: when a non-conservative points out something damning to the orthodoxy, and when a conservative says soemthing that reveals hypocrisy.
"So, then, gay marriagewill destroy society, but Abu Ghraib was perfectly okay?" "Why do you hate America so much?"
"I'm all for free enterprise, but when companies start offering domestic-partner benefits, free enterprise has gone too far." "Why do you hate America so much?"
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.
For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
