The high you get when you know you're about to get drugs to get you high. Usually occurs with people who have a dependency to a substance, i.e. heroin or cocaine.
"Man, I was so sick today until my girl called and said she was on her way. I instantly got a pre-high and felt so much better."
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!
