“Diss” (or “dis”) is slang for an insult or act of disrespect toward someone.

Core meaning

  • As a verb : to diss someone = to treat them with disrespect, insult them, or criticize them in a rude way.
* Example: “Why did you diss me in front of everyone?”
  • As a noun : a diss = an insulting comment, action, or put‑down.
* Example: “That comment was a straight diss.”

Where it comes from and how it’s used

  • The word comes from “disrespect,” shortened to “dis/diss,” and became common in African American slang and hip‑hop culture before spreading widely.
  • In rap and online culture, a “diss” can be:
    • A sharp one‑liner or comeback.
    • A “diss track” – a whole song made to insult or mock another artist.
  • People also use it casually in everyday life:
    • “Don’t diss my music taste.”
    • “Ignoring him like that was a diss.”

Quick nuance

  • Not every criticism is a diss; a diss specifically has a disrespectful, belittling tone.
  • Because it’s meant to put someone down, repeatedly dissing people can slide into bullying or toxic behavior, especially online.

TL;DR: “Diss” means to disrespect or insult someone (verb), or the insult itself (noun), often used in music, internet, and everyday slang.
