A chemical reaction is when two chemicals (reactants) form to make a new chemical substance. During the chemical reaction, the atoms are rearranged to form the aforementioned new chemical substance (products).
There are different types of chemical reactions, however, in this definition, I will not be explaining them.
Guy 3: Woah, did you see that chemical reaction?
Guy 1: Hell yeah I did!
Guy 2: I wonder if we could do it again?
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!
