When a group of individuals known to only show for memes, show up to a thread, only to postmemes and bring absolutely nothing of substance to the discussion.
Fwafwow decided the thread was going nowhere, so he sent up the bat signal to team memehole.
A mental state you enter when you are stuck watching video after video or looking at meme after meme on Reddit, Facebook, Twitter, YouTube, etc. Eventually you realize you have to stop, yet you continue watching while simultaneously questioning life as a construct.
"This is my 15th Cyber 8 video in a row. What am I doing with my life?"
"Dude, you're in a memehole. Better get out before it's too late."
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.
