According to Kevin Smith and Jason Mewes the origin is this: When Jason was younger, about 14, he used the "nee"-expression as a means of countering a statement just made, as in "I'm gonna fuck your mom tonight - nee". The "nee"-expression then grew and grew, but always refering to the canellation of "charge" in a statement. Thus, snoogans means to not do anything. Just the same as Wayne's world's "not!"-expression. Of course the snoogans works excellent as a stand alone-expression, but the "true" ethymology is the one stated above.
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!
