The unwritten rule that comes into effect when McDonald's temporarily changes the price of all fountain soft drinks to $1 for summer.
The rule states that one MUST purchase a large-sized drink, regardless of the situation. In theory, this is to avoid possible fear of needing to drink more and teasing. Some may even buy a large drink simply because they are afraid of not getting every penny's worth of soda.
A: Hold on Jeff, let me go get a large coke.
B: I thought you were trying to lose weight.
A: Hey, it's cheap, and that's why I'm getting one.
B: Why get a large though?
A: Dude, it's the McSummer rule!
B: Whatever. You're not actually gonna drink the whole thing are you?
A: 'course not........just don't question it.
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!
