What does null mean?
Before you tell me to look it up, I have and nothing answers my question from what I've found. On any video I watch on YouTube, there's always someone that comments "null" and I have no clue what it means.. Why do people comment this on videos and what does it mean?

`null' is a concept related to the absence of value. There's a bunch of different meanings depending on context; mathematics, computer science, literature, etc. all have slightly different meanings of `null'.
In particular, mathematics supports the notion of the null set, i.e., the set `{}'. The null set has no elements.
`null' is not similar to zero as a concept:
if a variable `x' holds the value `0', `x' is not null because it has a value. If we introduce a unbound variable `y' with no value, then the value of `y' is null because it is not equal to anything: `y' has no value.
In legal usage, a `null (and void)' action, document, etc., is treated as if it never existed; it's totally ignored as it has no value and no legal effect.

If it doesn't make sense, *ignore it*! YouTube commenters are not the smartest.
Maybe they're just trolling you or other viewers. Maybe it's a poorly-written spambot that couldn't find what it was supposed to post (and thus posts "nothing"). Maybe they have no opinion, but couldn't resist the urge to post a useless comment.
