Ever been scrolling through a comment section or reading a message and suddenly bump into someone saying something like “that rule feels so arbitrary” — and you pause for a second wondering, wait… what does arbitrary even mean?
It happens to almost everyone. You see a word used so confidently that you feel you should already know it… but nope, it doesn’t ring a bell.
I remember the first time I read “arbitrary decision” in a forum debate and spent a full minute pretending I knew what was going on before finally looking it up.
So here’s the quick answer:
Quick Answer: Arbitrary means “based on personal choice, preference, or randomness rather than logic or rules.” It’s a neutral-to-slightly negative way of saying something feels random, unfair, or without clear reason.
What Does “Arbitrary” Mean in Text?
In texting, social media comments, and online discussions, arbitrary is used when someone wants to say that something seems random, unfair, unplanned, or not backed by a solid reason.
It’s not slang — it’s an actual English vocabulary word — but it’s extremely common in online conversations.
Example sentence:
“Giving extra marks to only three students felt arbitrary because the teacher didn’t explain why.”
In short:
Arbitrary = random/unfair = done without logic or clear reason.
