What you do when you've been in the sun for a while, you're hot and/or uncomfortable, and you need some shade. Shadowbathing is the opposite of sunbathing; it results in a nice cool feeling that is comparable to eating a freezepop with your entire body.
Yo Erica, we've been playing frisbee in this heat for four hours...let's break for lunch and do some shadowbathing.
Phantom masturbation as you see a lot of people use nowadays. The participant acts as if they are masturbating and sometimes concludes with a fake ejaculation. It is usually used as sarcasm or a way to show displeasure. The word is a play on the boxing technique of shadowboxing.
Tom: Rick, you look like a transvestite.
Rick: *acts as if he is masturbating*
Tom: Quit shadowbating.
Extended version of muskedunder:
A privileged way to identify an enormous individual in terms of bodyfat. So large that the individual casts a large shadow over everything in its proximity.

Some other dude to his friend:
"Damn! It got really dark so quickly. Is it an ongoing solar eclipse at the moment?"
"Nah man! Look. It's gotta be that Shadowcasting Muskedunder rolling by."
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!
