if used as a figurative (of a text), then dense means it's hard to understand because of a complexity of ideas...

if dense is used as figurative (of a person), then dense means that it's difficult to explain anything to that person because they can't make sense of complex ideas (because their head is too "dense" or "thick" to get anything through)

It does not mean stupid although it is often used to describe people who are also stupid. For example, a lawyer who argues what the word "is" means could be described as dense. Stupid is lacking in intelligence whereas dense infers that a person's head is too thick to teach anything to him/her.

People who exhaust you by asking for further clarification on anything from policies and procedures by asking questions they wouldn't ask had they understood your previous answer to one of their previous questions are dense - their skulls are too thick to get anything through to their heads so they don't understand even the simplest lowest common denominator definitions!

A dense person is the opposite of an airhead, although about as useful.
If you had to read this definition several times to understand it - and you still don't really understand it, it is because you are dense.

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!
