The phrase "to be honest" is often used as a filler which makes a sentence run on. It is often perceived that one who uses such phrase implies that they often are not honest, so they feel the need to say "to be honest" when they actually are being honest.
Filler phrase so you can quick come up with a random statement. Often followed by a very unthoughtful statement that the person did not in fact mean to say.
Other ways it can be used is if you are in fact trying to be honest.
1. To be completely honest, I really think you complain too much... Wait I didn't phrase that right!
2. Gavin-To be completely honest, saltwater is actually okay to drink large amounts of.
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!
