Shaytards 

The concept began in March of 2009, when Shay's viewers were complaining that he wasn't posting videos very often, and Shay began to feel bad. As sort of a "punishment", he decided to post a video everyday for a month, and if he missed a day, he would delete his famous Shaycarl channel. It became a year. Which became just everyday.

Through watching the videos, we learn many things about the Tards. Shay and his wife, nicknamed Katilette (or mommytard) have 4 children. For security reasons, Shay and Katilette do not purposley let out their childrens names, so they are given "tard" names. The oldest child is Sontard who is six, five year old Princesstard, three year old Babytard, and the newest edition, two month old Rocktard. They also have a dog named Malachi.

These videos have become part of many people's daily life, and routine. Many of their videos have delt with serious issues, like when Princesstard realized that someday she was going to die. Or when Rocktard was born. We've seen them all laugh, cry, scream, but what sets them apart from most families is how close they are. They are always laughing and having fun with each other, and they love each other more than anything in the world.
Mike: Yoo, did you see the new Shaytards video?

Carol: No! What happened?

Mike: Sontard fell off his bike and landed on babytard!

Carol: No way! I'll have to watch when I get home!

Surf Dracula Syndrome 

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!
